Thermo SIG carries the responsability to define the tests to which a Property Package is submitted to verify that its implementation conforms to the Thermodynamic and Physical Properties interface specification in version 1.1.

Thermo SIG reviewed the detailed specification of tests to be performed on implementations of the ICapeThermoUniversalConstants interface specification, a part of the Thermodynamic and Physical Properties interface specification in version 1.1. Only implementations on Property Packages are considered. The document was prepared by Michel PONS before the meeting. This test specification is applicable to the future version 0.2.2 of the CO-LaN Test Suite.

Thermo SIG decided to move three tests, currently listed as compliance tests, to the list of tests verifying that best practices are followed. These three tests verify the consistency between, on one side, the list of universal constants supported by a Property Package, and, on the other side, the list of supported constant properties for pure compounds and the list of supported single-phase mixture properties.

A few modifications were also applied to the logic applied in tests like testing not only that supported universal constants, as defined in the CAPE-OPEN standard, return real values, but also that the returned values are defined numbers. Also Thermo SIG decided to introduce the handling of additional exceptions raised by methods invoked within the execution of tests. Additionnally, the rule that non-random input must be used in tests was re-affirmed and applied.

Next meeting of Thermo SIG is scheduled for November 8, 2022.

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.
