Coverage Issues

This page is supposed to provide an overview of remaining issues for all tested libraries. Therefore, failing models can get grouped by issue and short analyses and existing tickets can be added to guide the bug-fixing process.

#3729	Models of trunk/Modelica that do not simulate in OpenModelica (and are not present in MSL 3.2.1 failed simulations)	new		somebody	defect	Future

Following 5 models are missing for the full coverage of the cRuntime here.

Modelica.Electrical.Machines.Examples.AsynchronousInductionMachines.AIMC_YD
- fails with alarm clock
- works in our testsuite, because omcTearing is used
- IndexReduction seems okay
- works with a different sorting -> +preOptModules+=sortEqnsVars
- -> probably really a tearing issue of select corrent iteration variable

Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMEE_Generator_MultiPhase
- singular linear system while simulation, initialization is solved via totalpivot
- works with different sorting -> +preOptModules+=sortEqnsVars or other remove simple equation module +removeSimpleEquations=none|new
- fails without tearing
- -> most likely an IndexReduction issue #3691

Modelica.Electrical.Spice3.Examples.Spice3BenchmarkDifferentialPair
- Combination of Nonlinear and Dassl > initialization passes -> solver
- the algebraic loops differs a lot compared with dymola 52 varibale and we have 29.
- IndexReduction seems okay.
- -> perhaps bad algorithm handling

Modelica.Fluid.Examples.Explanatory.MomentumBalanceFittings
- non-linear system fails at initialization
- dymola also struggles with it
- -> stream handling, non-linear solver issue or model error

Modelica.Fluid.Examples.HeatingSystem
- non-linear system fails at initialization
- has dynamic stateSelection, but even with "stateSelect" always on dymola states it fails.
- non-linear problem that fails is mixed
- homotopy is used
- -> perhaps mixed non-linear problem or homotopy handling
