2561	Misleading Errormessage for singular inital system	Jens Frenkel	Lennart Ochel	"If a Modell has a singular initial system (because of the model or a bug in the compiler) the first error message is:

{{{
Error: Das Modell ist strukturell singulär. Fehler wurde gefunden durch Sortieren der Gleichungen 
 4: z = 2.0 * time;
1: z = 4.0;
 für Variablen 
 y(2), x(4), z(1)
Error: Interner Fehler Transformation Module PFPlusExt index Reduction Method Pantelides failed!
}}}

the following warning:
{{{
Warning: No system for the symbolic initialization was generated. A method using numerical algorithms will be used instead.
}}}
nobody reads anymore. But in such a case the messages is totaly misleading. There should be a message that the inital system is singular and not the system for time simulation."	defect	closed	blocker	1.9.1	Backend	trunk	fixed		casella@… Willi Braun Dirk.Zimmer@… Volker Waurich Christian Schubert Adrian Pop
