=title=
Differential-algebraic Equations in Process Simulation
=abstract=
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.
