Same model different number of equations
Same model different number of equations
Mar-30-13 16:47:57
Below I enclose the model "QSAsma" in a file of its own (model.mo) and in a package (package.mo).
OM reports 221 variables.
OM reports for the model in model.mo 222 equations, for the model in package.mo 228 variables.
Dymola always reports 221 variables and equations.
When this model is simulated in OM (called by other models) OM complains about it having too many equations.
I see two issues:
1) is it possible that for THE SAME model a different number of equations is counted when inside or outside packages?
2) maybe something is wrong also in the model.mo equations counting (222 instead of 221)?

Thank you
Re: Same model different number of equations

What command did you use to count the number of equations in OpenModelica? If you used checkModel(), note that the count is way off since it does not handle array-equations correctly.

Re: Same model different number of equations

I used "check model" in OMEdit.
This "equation number" issue is blocking, since when I use the proposed model as a submodel of something "runnable", I receive the following message
Symbolic 19:02:42 0:0-0:0 Too many equations, overdetermined system. The model has 546 equation(s) and 539 variable(s)
and simulation does not start.
