Thermo SIG went over the comment made by Richard SZCZEPANSKI on the specification of tests on implementations of the ICapeThermoUniversalConstants interface. More precise references to the Thermodynamic and Physical Properties interface specification document were introduced throughout the document specifying tests.

Thermo SIG addressed the issue that the Thermodynamic and Physical Properties interface specification, as published, contains many errors and is inconsistent in many places. One of the most evident is the possibility left for most of the methods to return a CAPE-OPEN exception ECapeNoImpl to state that a method is not implemented. Since Compliance Tests are written in such a way that any exception raised leads to a Test failure, there is a major inconsistency between the contents of the Thermodynamic and Physical Properties interface specification and the way compliance tests need to be designed.

The Tests should be designed to verify that the current implementations are correct in achieving interoperability even if the Tests do not relate exactly to the interface specification. Thermo SIG needs to focus on listing the Tests to be done, not on specifying in details the Tests. In this way Thermo SIG will not be the bottleneck in the development of the CO-LaN Test Suite. In parallel a very complete Errata & Specifications document has to be written up so that Tests may make reference to it.

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.
