Reduction of a differential algebraic equation (DAE) system to an ordinary differential equation system (ODE) is an important step in solving the DAE numerically. When the ODE is obtained, an ODE solution technique can be used to obtain the final solution. In this paper we consider combining index reduction with projection onto the constraint manifold. We… (More)
This paper proposes a novel data structure for equation-based plant models. The data structure facilitates the plant modelling process starting from physics-based component creation through model simplification to Modelica model export.
