Differential-algebraic equations, which are systems of differential equations and algebraic constraints, occur in mathematical models of physical or engineering systems. Specific algorithms for numerical integration of such systems have been designed. Also, software packages dedicated to various domains of physics and engineering have been developed. We present here the status of the development of a system that consists in a compiler for a special modeling language - Modelica. We also discuss possible directions to use symbolic computation, in order to extend the system to allow automatic generation of Kirchoff laws.
