Thermo Special Interest Group met on May 16, 2023 from 11 am till half past noon (Central European Summer Time).



AmsterCHEM (represented by Jasper van BATEN), BASF (represented by Sergej BLAGOV), KBC (represented by Richard SZCZEPANSKI), University of Cape Town (represented by Klaus MÖLLER), Michel PONS (Consultant as Chief Technology Officer).


Thermo SIG focused first on topics that could be covered at CAPE-OPEN 2023 Annual Meeting. As reported by Sergej, reliance on Python seems to increase in the industry, a trend that Richard confirmed through multiple requests received from clients of KBC. Klaus reported that the Julia programming language receives also wide support at University of Cape Town as well in industrial companies operating in the Republic of South Africa. Kind of 50-50 split between use of Python and use of Julia.

This may help support the request for a Python language binding in COBIA, to be consolidated with adequate findings on speed achieved by COBIA versus COM. However Jasper reported that Python and Julia may very well be considered obsolete very soon, displaced by Mojo as an easy-to-use and high performance language. Mojo enables systems-level optimizations and flexibility that unlock the features of any device in a way that Python cannot. Sergej, Jasper, Richard and Klaus will gather the pieces of information they have access to so that they may propose a paper at the CAPE-OPEN 2023 Annual Meeting. Such a paper could trigger further steps in COBIA Phase III development program.

Next Thermo SIG addressed remaining modifications in section 5.2.4 of the Thermodynamic and Physical Properties Interface Specification. Especially the conversion between compound flows on one end and total flow rate and fractions was tacled, reaching a common wording on the new part of section 5.2.4. This modification calls for further modifications in the notes describing several methods of ICapeThermoMaterial interface.

Next conference call is scheduled for May 23, 2023.

Contact the co-leaders of the SIG for further information: Sergej BLAGOV at BASF () and Jasper van BATEN at AmsterCHEM (). The Thermo SIG is looking for additional parties, well versed into any aspect of thermodynamics applied to process simulation and willing to contribute to the maintenance and development of CAPE-OPEN interface specifications related to thermodynamical aspects.
