 Modelica is a freely available, object-oriented language for modeling of large, complex, and heterogeneous physical systems.
 It is suited for multi-domain modeling, for example, mechatronic models in robotics, automotive and aerospace applications involving mechanical, electrical, hydraulic and control subsystems, process oriented applications and generation and distribution of electric power.
 Models in Modelica are mathematically described by differential, algebraic and discrete equations.

 Many Modelica models, especially in the associated Modelica Standard Library, are higher index systems, and can only be reasonably simulated if symbolic index reduction is performed, i.e., equations are differentiated and appropriate variables are selected as states, so that the resulting system of equations can be transformed to state space form (at least locally numerically), i.e., a hybrid DAE of index zero.
 In order to allow this structural analysis, a tool may reject simulating a model if parameters cannot be evaluated during translation -- due to calls of external functions or initial equations/initial algorithms for \lstinline!fixed = false! parameters.
 Accepting such models is a quality of implementation issue.
