DASSL broken in trunk

[Christoph Höger]

this small model won't simulate using my bootstrapped version of omc:

  model DASSLBug

    import Modelica.Electrical.Analog.Basic.{Resistor, Capacitor, Ground};
    import Modelica.Electrical.Analog.Sources.{SineVoltage};

    SineVoltage src;
    Resistor w1, w2;
    Capacitor c;
    Ground g;

  equation
    connect(src.n, w1.p);
    connect(src.n, g.p);
    connect(w1.n, c.p);
    connect(c.n, w2.p);
    connect(w2.n, src.p);

  end DASSLBug;

I am on OpenModelica 1.9.0 beta4+dev (r15940)

[Martin Sjölund]

Can you give more information? The bootstrapped compiler works fine for me:

omc ++v && omc +s a.mo Modelica ModelicaServices > /dev/null && make -f DASSLBug.makefile && ./DASSLBug ; echo $?

Sorry, forgit to attach the simulation result:

That model works for me also. Which OS do you use?

[Martin Sjölund]

I think this is the same error I have seen on some OSX versions. If I remember correctly, related to using 32-bit versions of omc?

Postponed until 1.9.1

[Martin Sjölund]

This ticket was not closed for 1.9.1, which has now been released. It was batch modified for milestone 1.9.2 (but maybe an empty milestone was more appropriate; feel free to change it).

[Martin Sjölund]

Milestone changed to 1.9.3 since 1.9.2 was released.

[Martin Sjölund]

Moved to new milestone 1.9.4

[Martin Sjölund]

Milestone pushed to 1.9.5

[Martin Sjölund]

Milestone renamed

[Francesco Casella]

If DASSL was still broken, we'd have heard very loud complaints. I assume this issue has been solved long time ago.
