IndexReduction.differentiateEqns failed

[anonymous]

occurs with the follwing models:

• Modelica.Electrical.Spice3.Examples.Graetz
• Modelica.Fluid.Examples.HeatingSystem
• Modelica.Magnetic.FluxTubes.Examples.SaturatedInductor
• Modelica.Magnetic.FluxTubes.Examples.SolenoidActuator.ComparisonPullInStroke

[Jens Frenkel]

All models pass the index reduction if Variables with stateSelect=StateSelect.prefer not changed to States and the first two if final Parameters are evaluated before index Reduction.

The first one pass also if variable with stateSelect=StateSelect.prefer changed to State

[Jens Frenkel]

Modelica.Fluid.Examples.PumpingSystem - StateSelect.prefer pumps.medium.p should be algebraic

Modelica.Fluid.Examples.HeatingSystem - StateSelect.prefer

[Jens Frenkel]

Modelica.Fluid.Examples.InverseParameterization.mos StateSelect.prefer pumps.medium.p should be algebraic

[Jens Frenkel]

Modelica.Magnetic.FluxTubes.Examples.SaturatedInductor StateSelect.prefer coil.i should be algebraic

[Jens Frenkel]

Hack for the models in BackendDAECreate.lowerVarkind

        s = ComponentReference.printComponentRefStr(inComponentRef);
        //false = intEq(System.strcmp(s,"pumps.medium.h"),0);
        //false = intEq(System.strcmp(s,"pumps.medium.p"),0);
        false = intEq(System.strcmp(s,"coil.i"),0);

Modelica.Electrical.Spice3.Examples.CascodeCircuit, unnecessary differentiation

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

[Martin Sjölund]

Ticket retargeted after milestone closed

[Martin Sjölund]

Milestone moved to 1.12.0 due to 1.11.0 already being released.
