final parameter in ComparisonQuasyStationary.mo

[Volker Waurich]

Hi,
the parameter simpleSolenoid.coil.N in the model

Modelica.Magnetic.FluxTubes.Examples.SolenoidActuator.ComparisonQuasiStationary.mo

from msl 3.2.
should be declared as a final parameter:

Modelica.Magnetic.FluxTubes.Basic.ElectroMagneticConverter coil(final N=N, i(fixed=true))

but in daelow its not final:

197: simpleSolenoid.coil.N:PARAM()

I have committed a fix for this now, but have not enabled it yet since it seems to break some things in the backend. To enable it, simply uncomment the call to InstUtil.propagateModFinal in InstVar.instScalar. These tests needs to be fixed first though:

simulation/libraries/msl31/Modelica.Electrical.Machines.Examples.DCSE_Start.mos
  Simulation result not equal for der(dcse.la.i)

simulation/libraries/msl32/Modelica.Magnetic.FluxTubes.Examples.SolenoidActuator.ComparisonQuasiStationary.mos
  Gives a warning about alias set with several free start values. I don't know how bad this is.

simulation/libraries/msl32/Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMEE_Generator_MultiPhase.mos
simulation/libraries/msl32/Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMPM_Inverter_MultiPhase.mos
simulation/libraries/msl32/Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMR_Inverter_MultiPhase.mos
  Error when solving linear system.

simulation/modelica/msl22/Test3PhaseInitOver.mos
  Over-determined initial system has changed, several variables have been replaced 
  with zeros in the printed equation. I don't know if this is an issue or not.

Thanks a lot. I will check the magnetic models.

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

[Per Östlund]

Some of broken models are now working. The remaining models are:

simulation/libraries/msl32/Modelica.Magnetic.FluxTubes.Examples.SolenoidActuator.ComparisonQuasiStationary.mos
simulation/libraries/msl32/Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMEE_Generator_MultiPhase.mos
simulation/libraries/msl32/Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMPM_Inverter_MultiPhase.mos
simulation/libraries/msl32/Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMR_Inverter_MultiPhase.mos

The issues are the same as before.

Ticket retargeted after milestone closed

[Martin Sjölund]

Milestone moved to 1.12.0 due to 1.11.0 already being released.

[Francesco Casella]

The milestone of this ticket has been reassigned to "Future".

If you think the issue is still valid and relevant for you, please select milestone 1.13.0 for back-end, code generation and run-time issues, or 2.0.0 for front-end issues.

If you are aware that the problem is no longer present, please select the milestone corresponding to the version of OMC you used to check that, and set the status to "worksforme".

In both cases, a short informative comment would be welcome.

[Per Östlund]

With the new frontend the parameter is declared as final, so I guess we can consider this fixed.
