open modelica crashing while simulating the code file

[bansodanurag@…]

the model Ex2_6_1
solved by rungakutta method for range x>0
Real x,y;
equation
(x*y+y^{2 +x}2)-der(y)*x^{2=0;
x= time;
end Ex2_6_1;}

attached code makes the omedit crash

Seems to work fine in the Linux master. @Adeel: Is this one of the crashes that was already fixed in beta3?

[Adeel Asghar]

Simulate with Rungakutta and plot y.
Simulation works fine for me. It crashed when plotting y. Don't know why.

[Lennart Ochel]

I guess the result file is corrupted.

[Lennart Ochel]

Yes, the result file contains inf for y and der(y).

[Martin Sjölund]

That shouldn't cause a crash though. Fix OMPlot :)

[Lennart Ochel]

OMPlot doesn't crash at all.

Replying to sjoelund.se:

Agreed. Perhaps need to check NaN.

It does. Run OMPlot --filename=result.mat y

[Lennart Ochel]

OMPlot y doesn't crash. It just shows an empty plot window. I will try to prevent writing inf into a result file.

OS dependent? I tested it using Linux.

[Lennart Ochel]

This should no longer cause a crash. However, this model does also not simulate anymore because we now catch inf which gets calculated for der(y) during simulation.
