Liquid and Gas sub-packages should probably have more general base classes

2

The ThermofluidStream.Media.myMedia.GasAndIncompressible.PartialGasAndIncompressible class contains the following code: https://github.com/DLR-SR/ThermofluidStream/blob/38553ffdb79f8d65566b06c46249a14605eca1e9/ThermofluidStream/Media/myMedia/GasAndIncompressible/PartialGasAndIncompressible.mo#L17-L20 This works fine as long as there is only one medium JP8DryAir that extends this base class and has the same redeclares...

Functions with wrong type argument called in new tank models?

5

Many of the recently added models, e.g. `ThermofluidStream.Boundaries.Tests.TankExtendedTest2` fail in OMC with this error ``` [ThermofluidStream 1.1.0-main/Boundaries/Internal/partialTank.mo:126:3-127:39:writable] Error: Type mismatch for positional argument 1 in ThermofluidStream.Boundaries.Tests.TankExtendedTest2.tank.Medium.Liquid.density(state=tank.medium.state). The argument has type:...

Experiment annotations have no effect in OMJulia

2

@olivleno reports: When calling: `result = OMJulia.API.simulate(omc, test_model; simflags="-lv=-LOG_ASSERT", outputFormat = "csv")` the experiment annotations take no effect.

Invalid generated code because the NB generates a Complex residual for an algebraic loop.

4

Please check [PowerGrids.Examples.IEEE14bus.IEEE14busPowerFlow]( https://libraries.openmodelica.org/branches/newInst-newBackend/PowerGrids/files/PowerGrids_PowerGrids.Examples.IEEE14bus.IEEE14busPowerFlow.err) with the NB. The C code compilation fails because of invalid C code. According to @phannebohm (see [comment](https://github.com/OpenModelica/OpenModelica/issues/12628#issuecomment-2348938027)) this happens because the NB generates a Comples...

TransmissionLineEquations models built with NB cause IDA to fail due to bogus causalization

9

Please check [ScalableTestSuite.Electrical.TransmissionLine.ScaledExperiments.TransmissionLineEquations_N_10](https://libraries.openmodelica.org/branches/newInst-newBackend/ScalableTestSuite_noopt/files/ScalableTestSuite_noopt_ScalableTestSuite.Electrical.TransmissionLine.ScaledExperiments.TransmissionLineEquations_N_10.sim). The model is initialized successfully, but then fails with ``` ##IDA## -3 error occurred at time = 0 ``` According to the `IDA documentation` -3 is IDA_ERR_FAIL,...

Issue with --fmiFilter

6

@rfranke reports: `--fmiFilter` causes issues with export of discrete states cross references to e.g. previous. Possibly also with ModelStructure. The root cause is that FMI refers to indices in the...

Allow to modify parameters and replaceable classes of the model itself in OMEdit

1

### Description When visualizing a model's diagram, OMEdit allows to modify the parameter values of models instantiated within it, by double-clicking on their icons and showing parameter input masks. However,...

FlexibleBeam models in ScalableTestSuite fail with --daeMode because of time event handling

26

The FlexibleBeam models of the ScalableTestSuite library are currently broken when ran with `--daeMode`, see e.g. [FlexibleBeamModelica_N_2](https://libraries.openmodelica.org/branches/newInst-daeMode/ScalableTestSuite_noopt/files/ScalableTestSuite_noopt_ScalableTestSuite.Mechanical.FlexibleBeam.ScaledExperiments.FlexibleBeamModelica_N_2.sim): ``` assert | debug | ##IDA## discrete update failed flag -6! ``` They...

Incorrect handling of algorithms with arrays by the backend

32

@kabdelhak, while investigating [#6199](https://trac.openmodelica.org/OpenModelica/ticket/6199) and [#6207](https://trac.openmodelica.org/OpenModelica/ticket/6207), I stumbled upon something weird related to how algorithm sections involving arrays are handled by the backend. I could reproduce the issue (or a...

Provide appropriate nominal values to derivatives for proper scaling of iterative nonlinear solvers

12

### Description In some cases (see e.g. #7734) derivatives are involved in nonlinear strong components. If not solved with the appropriate precision, they may fool the ODE solvers's error control...
