Can You Believe It?  Ten years of CAPE-OPEN!

Yes, it's been 10 years since the CAPE-OPEN concept was but a glimmer in the eyes of the likes of Hans-Horst Mayer (BASF) and Peter Banks (BP). They met in 1994 in Snowmass, Colorado, USA at a FOCAPD meeting. Peter Banks recalls that key people at BP had been thinking for some time about the value of having a plug and play standard for process simulation. Peter thought that FOCAPD seemed like a good place to discuss this concept with the process simulation community. Unfortunately, it didn’t raise much interest at that time, but, as it turned out, it did raise just enough. Hans-Horst, and by extension BASF, stood up and strongly supported it!

BP got support from the EU project PRIMA to submit a plug and play proposal to the EU’s Framework IV. At the same time, the German IK-CAPE consortium was proposing to submit a very similar proposal as a result of Hans-Horst’s persuasion and persistence in that organization. Both proposals were merged and after much struggle, which was led by Siegfried Nagel of Bayer, eventually became known as CAPE-OPEN. The leadership role passed to IFP and Bertrand Braunschweig in 1996. This was at a critical point in the campaign to get the project approved by the EU, which culminated in the inauguration of EU CAPE-OPEN project in 1997.

By the end of the European CAPE-OPEN project in mid-1999, there had been a lot of progress, though to many that progress did not seem nearly enough. Some would claim that the only result of the effort was the "semi-interoperable" mixer-splitter demo that AspenTech and Hyprotech produced and that was first demonstrated in public during the ESCAPE-9 conference in Budapest. In fact, RWTH Aachen, INPT Toulouse, Imperial College/PSE and IFP put together a distributed process model with CheOps (RWTH), a gPROMS solver, a SMST package (INPT) and a unit operations model from IFP. In addition, and of central importance, Version 0.9 of the CO standard was released - a draft standard, but with key elements in place. So the doubters were wrong in the first instance, but history would prove them wrong in spades. In fact there were three other huge results from the CAPE-OPEN project:

  1. The Global CAPE-OPEN (GCO) project, which continued the efforts to develop a functional CAPE-OPEN standard, providing the 0.90 standard that was commercially implemented in Aspen Plus and HYSYS in late 1999 and early 2000. The work in CAPE-OPEN showed those who believed that indeed, CO was possible.
  2. The extensive groundwork done by the various work packages that prepared the way for the full implementation of the CO standard in HYSYS and AspenPlus. This body of technical information continues to produce dividends even today.
  3. Undeniable proof that a broad consortium of users, software developers, and academics could work together in common cause, sort out their differences, and get something done!

The Global CAPE-OPEN project, running from July,1999 to March 2002, funded by the European Commission and again led by IFP and Bertrand, iced the cake. Standing on the shoulders of the work done in CAPE-OPEN and expanding to include participants from Japan and North America, GCO also delivered. Version 1.0 of the CO standard, continued cooperation among all the players, and the CAPE-OPEN Laboratories Network (CO-LaN) all showed the challenge had been met.

The CO interface standard is now the way to do interoperability in process simulation. A recent issue of Chemical Processing magazine has highlighted the progress and the future. Progress continues as the CO-LaN Special Interest Groups (SIGs) address the needs for improvement and expansion of the standard. More and more process software is CO compliant, so the value creation prospect continues to expand. The CO-LaN continues to look after the maintenance and extension of the standard, with leadership passing from IFP to Dow and Werner Merk in 2004.

As always, we owe a lot to those who have gone before. The summary above does not identify the many technical experts in the software vendor companies, operating companies, and academic institutions, without whose expertise, cooperation and considerable efforts none of this progress would have been possible. Their names are to be found on the specifications and other technical documents listed on the CO-LaN website. Fortunately, many of these folks continue to contribute to "the cause." The next time you get a chance, give them a hearty "thank you" for bringing us literally into the 21st century!

DIPPR 801 Database Ready to Release CO Compliant Version

The first version of the CO compliant interface for the DIPPR 801 pure component database was released for DIPPR internal testing on September 1st 2004. The DIPPR 801 compliant software interface was produced by Virtual Materials Group based on the Open Interface Specification - Physical Property Data Banks (PPDB), 22nd November 2001 and includes the following software interfaces.


This register knows the DIPPR 801 database and tells the clients that the database is accessible. It is managed by the system administrator, not the client users.


Used to explore the 801 database by finding compounds, dictionaries, database structure, and bibliography.


Used to extract data table topology and actual data from the 801 database using the CAPE-OPEN defined tabular format.


Used to extract information about models used in the 801 database as well as model description and model parameters.

The interface was written in Microsoft Visual C++ Version 6.0 and it is COM compliant. The full source code was released to DIPPR as well as the user's manual and a complete set of examples showing how to use the interface using Visual Basic.

Aspen-Fluent Integration Software Wins 2004 R&D 100 Award

Fluent Inc., the world leader in computational fluid dynamics (CFD), recently won a prestigious 2004 R&D 100 Award for the novel integration of two best-in-class simulation software packages. The integrated simulation packages, used by many engineers in the process industries, are Aspen Plus®, process flowsheet modeling software from Aspen Technology, and FLUENT®, CFD modeling software from Fluent Inc. The primary goal of the integration is to combine high-fidelity equipment modeling with plant-wide process modeling to enable rapid assessment of innovative new plants involving unique equipment (e.g. fuel cells, gasifiers, complex reactors). The interface enables a comprehensive assessment of how all equipment items work together in a process by allowing detailed fluid mechanics models to plug into the overall flowsheet.

Process industries face the challenge of designing chemical, oil/gas, and power plants to operate efficiently and with near-zero emissions, while performing profitably. The Aspen Plus-FLUENT Integration Toolkit couples process simulation and computational fluid dynamics (CFD)-based equipment models for improved analysis, design, and plant optimization.

The Toolkit combines two commercial simulation systems by using CAPE-OPEN interfaces: Aspen Plus, a process modeling software for the chemical, pharmaceutical, and power industries, and FLUENT, a CFD software for detailed flow analysis of process equipment. Competitive technologies are based on university software or research-oriented, non-commercial endeavors. The benefits of an integration based on commercial products include wider breadth of capabilities, and enhanced product security. Another advantage is the potential to bring the technology more quickly to market.

This technology breakthrough enables engineers to conduct process simulations with both a scope and an accuracy never seen before. The toolkit will accelerate innovation, reduce capital costs, improve product yields, reduce energy consumption and reduce emissions. The Aspen Plus – FLUENT integration toolkit is expected to have a high impact on a wide variety of industrial applications throughout the process industries, including power generation, chemicals and polymers.


Fluent Inc. worked closely with Stephen Zitney at the National Energy Technology Laboratory (NETL) in West Virginia under a US Department of Energy cooperative agreement to develop and demonstrate this integrated piece of software. The software is now available commercially. “This Award is the result of an unprecedented collaboration between NETL, ALSTOM Power Plant Laboratories, Aspen Technology Inc, K. Joseph Cleetus and Igor Lapshin at West Virginia University, and Fluent Inc.,” says Dr. Madhava Syamlal of Fluent, the project leader, “We believe that it paves the way for more accurate simulations of complex process / power plants as hardware and software technologies grow ever more powerful in the next 10 years.”

CO-LaN Annual Meeting - 17-18 February, Como, Italy

The CO-LaN will celebrate the 10th anniversary of CAPE-OPEN (CO) on February 17th-18th, 2005 during its annual meeting in Como, Italy.  A CAPE-OPEN interoperability showcase and an interoperability workshop will take place on Friday February 18th.

The showcase will provide demonstrations of leading interoperable software components using the CO standard.  During the workshop, developers of CO-compliant Process Modelling Environments (PMEs) and of Process Modelling Components (PMCs) will have access to the best world specialists in CO interfacing technology, including the set of CO-LaN approved consultancy providers.

Exchanges will proceed in an informal way, so as to maximise time and resources devoted to technical subjects:

  • implementation tricks
  • remaining interoperability issues
  • use of testers and wizards
  • middleware and language-specific aspects (COM, CORBA, .NET, VB, C++, Delphi...)
  • etc.

End users will have possibilities to play around with CO PMCs, PMEs and development environments in order to understand what's "under the hood of CAPE-OPEN"

Join us as a provider or consumer of CO technology for what promises to be a very informative and productive workshop! Provide us your feedback on this event.  For more information, please contact CO-LaN President, Werner Merk at

CO-LaN BOD Meeting Minutes

CAPE-OPEN Laboratories Network - Management Board Meeting

28 September 2004. ATOFINA Technical Center, Lyon, France

Management Board members present:Ronald-Alexander Klein, Peter Banks, Werner Merk, Kerry Irons (part-time by phone), Bertrand Braunschweig, Hans Pingen, Michel Pons

  • Membership: Protechsoft have applied to become an associate member. This has been endorsed by the Board. Several other companies and organizations are considering joining the CO-LaN. BOD members are in discussion with them to confirm.

  • Consultancy Service: The CO-LaN List of Components to be supported under Consultancy Service Agreements was updated during the meeting.
  • Feedback from US EPA Workshop: The session attendance was high (20+) and participant discussions showed that they were better informed about CAPE-OPEN than anticipated and desired detailed training, rather than just a general introduction to the CO concept. Since detailed training is not the business of CO-LaN, at the insistence of the vendors, we have to discuss how to facilitate its provision in future CO days. All EPA workshop delegates provided feedback and it is clear that we have a core of good presentations for future CO days. EPA were pleased with the event and it will encourage them to make their own software compliant.
  • Future Dissemination Activities Plans & Proposals:
    • ESCAPE 15 – A paper by Michel Pons on the CO-LaN Consultancy Service.
    • Modelling of Complex Processes, Houston March 05 – A paper by Michel Pons on CO examples.
    • Journals - The first CAPE-OPEN article to be published in a national chemical engineering journal is about to be submitted in the Netherlands by Hans Pingen. Other articles will be submitted in the UK.
    • Training – In view of the experience at the EPA event, a generic framework for CO training is planned. There are two target audiences: software developers and end users. We need a summary of these objectives as a basis for discussion with approved consultancy providers and other software suppliers.
  • SIG Activities

    • Thermodynamics - AspenTech’s Type Library installer is substantially complete, but some details remain to be resolved.
    • Unit - Pascal Roux has prepared a proposal for a modification to the dynamic extension of the Unit spec.
    • Interoperability - A Focus Group meeting at BP Sunbury has produced some proposals to improve the interoperability exercises.  The main proposal concerns the development of a dynamic data reporting tool to assist with debugging interoperability problems. The hope is that this tool can be demonstrated in Como.

CAPE-OPEN Laboratories Network Management Board Meeting

17 June 2004.  BASF, Ludwigshafen, Germany

  • Management Board members present: Ronald-Alexander Klein, Peter Banks, Werner Merk, Kerry Irons (part-time by phone), Bertrand Braunschweig, Hans Pingen, Celeste Colantonio, Michel Pons

  • Membership: Air Liquide has agreed to join as a full member. The Board approved the application. Carnegie Mellon University has already been approved as an Associate member.
  • Contracts/Services: The Consultancy Service Providers contract has been signed and has already been used to assist AixCAPE with their Shortcut Toolbox. A secrecy agreement was quickly signed between AspenTech and AixCAPE, which can be used as a template for future applications. It enabled the work to be carried out without a physical meeting being needed.
  • Dissemination: The following shows the dissemination activities currently planned:

    • ESCAPE 15 – Important to encourage academics to credit CO properly, where appropriate. Celeste Colantonio will contact Prof Marquardt.
    • AspenWorld 2004 -
      • Michel Pons is preparing a paper in the Open Standards track
      • SolidSim is in the Steady-State Users track>
    • WCCE 2005 - Bertrand Braunschweig co-ordinating the New Computational & Numerical Strategies track.  Celeste Colantonio is proposing a paper and IFP/RSI are presenting on simulation on a cluster
    • US EPA Workshop - being held on 24/25th August in Cincinnati, with a pre-meeting with EPA on 23rd. Bertrand Braunschweig, Michel Pons, Kerry Irons and Ben Keeping (PSE) conducting the meeting, with AspenTech and SimSci also sending representatives. Notification on the workshop will be sent out as soon as possible, using AspenTech, CAST and EPA distribution lists. Formal announcement will be made by SAIC. Key EPA contact is Bill Barrett.
    • FOCAPD - Prof. Marquardt is presenting and it would be helpful if he would mention the AixCAPE Shortcut Toolbox. Bertrand Braunschweig will contact him and Prof. Pantelides, who is also presenting.
    • Journals - Articles should be submitted to national chemical engineering journals in an attempt to reach a wider audience.  A pilot will be tried in TCE in the UK. A draft will be circulated to the Board before submission.
    • Training - Jean-Pierre Belaud’s course will be run again this year. It would be valuable if other Universities would run similar courses or summer schools. No actions were agreed on this topic.
  • SIG Activities
    • Thermodynamics
      • Version 1.1 of the Standard has been extended for solids and is being prototyped by Technical University Hamburg-Harburg. Feedback is awaited.
      • The Board agreed that version 1.1 should be prepared for issue without the solids extension, since it represented a worthwhile improvement over 1.0.
      • The issue of Type Library management was raised. AspenTech have produced a Type Library installer, but this has yet to be agreed by all. The problem of incompatible implementations is causing interoperability issues and the Thermo SIG agreed to take the lead in resolving it.
      • RSI have discovered a multi-threading problem with Multiflash. This is an IT, rather than thermodynamic, problem.
    • Unit
      • Fantoft is implementing a dynamic unit in D-SPICE, which should be ready by end August.
      • RSI has implemented the thermo interface in a dynamic unit.
      • Both companies are implementing both PME and PMC facilities.
      • PSE will not be implementing a CO dynamic unit in 2004.
      • Will use experience with gPROMS to assist RSI with INDISS conversion to CO-compliance.
      • VTT want to create an EO dynamic unit
      • Save & Restore methods dropped in version 1.0 in favour of COM methods.
      • Paper in preparation for 7th World Congress in Chemical Engineering
    • Interoperability
      • PRO II testing of the version 7.0 beta will be done in Total in mid-July. Reports indicate that it solves many of the problems of the previous version.
      • A problem identified by AixCAPE with Testers again raised the general problem of how to keep the Testers up-to-date. This will be discussed at the next meeting, as already indicated.
      • The need for an Interface Reporting Tool has already been identified. A meeting has been arranged at BP with Michael Halloran to produce a draft functional specification, as a result of his extensive experience in debugging CO components. This draft will be circulated for refinement by the rest of the SIG. In parallel, AixCAPE have indicated an interest in producing such a tool, after reading about it in the last CO Update.
  • Website

    • Jörg Köller from Adduce GmbH was unable to attend, but he submitted an estimate for carrying out a variety of maintenance and development activities on the website.
    • Werner Merk has identified an alternative company that appears to offer a more cost-effective web hosting service. A decision will be reached at the next BOD meeting.
    • The current system was chosen because it apparently allowed simple input and editing by all members of the Management Board. However, this has not happened for various reasons and the alternative of having a single webmaster was discussed.
    • A Task Force (Bertrand Braunschweig, Werner Merk & Jens Schmidt) was appointed to look at the best way forward.
    • In view of the difficulties of migrating current website content to a new system, it was agreed to extend the Adduce contract to the end of November.
    • Werner Merk will request the current content on CD from Adduce and see if the site can be cleaned up as part of the regular maintenance payment.
  • Phone Conferences and Next Meetings

    The next Management Board meeting is scheduled for Lyon on September 27/28th 2004.

    The next phone conference will be on Friday July 16th at 4pm German time.

    The next General Meeting, which coincides with the 10th anniversary of the birth of CAPE-OPEN, will be in February 2005 and is currently planned to be at Lake Como in Italy.

The Board expressed its thanks to BASF for hosting the current meeting in Ludwigshafen.
