On Model Portability

With the software of various commercial providers becoming mature, portability of models and associated data comes higher and higher on the agenda. CAPE-Open has accomplished a compromise getting various players on the market to communicate and agree on generating and accepting wrappers for their process models and also thermo data, both key issues in the chemical engineerings software world. Improving a step beyond wrappers requires a more basic approach, which allows to take advantage of the model structure. The design method and the used representation of the Modeller project have already proven a great degree of portability as models can be mapped into all major solver environments including Matlab, gProms, and other DAE solvers. We attempt to line out the motivation, the present and the future of this approach.
