Process Simulation and Analysis with Heterogeneous Models

摘要

This paper describes how symbolic techniques can be applied to general Fortran code in order to perform automatically many tedious, time-consuming, and error prone tasks required when using state-of-the-art algorithms for numerical calculations. Using this new approach, external models written in Fortran can be properly incorporated into an equation-oriented modeling environment. This allows the modeler to create heterogeneous models using both Fortran and the high level input language of the process simulator, depending on which is more suitable for the particular facet of the overall model.
