Abstract:The industrial usage of the open-source Modelica tool OpenModelica was limited so far for power plant applications; due to performance of the large fluid systems. This paper presents some efforts to improve the simulation time on benchmark fluid models proposed by Siemens Energy. The main aspects presented here to achieve a faster simulation are an efficient evaluation of the jacobian matrix by a coloring technique; that expolits the sparsity pattern of a modelica model. Therefore the techniques are scratched and applied to benchmark models provied by Siemens Energy.
