When simulating ME-FMUs with OMSimulator using CVODE, the timestepping mechanism is reset at each time step, restarting from a very small value. This only makes sense if an event was...

OMSimulator has [many flags](https://openmodelica.org/doc/OpenModelicaUsersGuide/latest/omsimulator.html#omsimulator-flags), which are output by calling `OMSimulator --help`. These flags all have default values, set by [oms::Flags::setDefaults()](https://github.com/OpenModelica/OMSimulator/blob/c920c759070def9ee61449dc2eb4b944bdaea328/src/OMSimulatorLib/Flags.cpp#L64), which are however not visible from the documentation. We should...

AixLib contains models with experiment annotation that have parameters without bindings and without explicitly set start values.

Dear AixLib developers, please check the latest OpenModelica [regression test report](https://libraries.openmodelica.org/branches/history/master/2024-03-06%2022:42:24..2024-03-07%2022:25:06.html). For the latest released version of AixLib ([AixLib](http://libraries.openmodelica.org/branches/master/AixLib/AixLib.html)) and for the development version of AixLib ([AixLib_dev](http://libraries.openmodelica.org/branches/master/AixLib/AixLib.html)) there are about...

This OpenModelica regression report points out something went wrong with the latest commits to AixLib. There are several models that now fail with the same [error](https://libraries.openmodelica.org/branches/master/AixLib/files/AixLib_AixLib.ThermalZones.ReducedOrder.Examples.ThermalZoneAirExchange.err): ``` Error: Variable poolParam.heiWav...

Please try the following MWE ```modelica model TestFunctionDefault package Medium = Modelica.Media.Air.SimpleAir; Medium.SpecificEnthalpy h = Medium.specificEnthalpy_pT(1e5, 300); end TestFunctionDefault; ``` The NF complains; ``` [1] 19:25:14 Translation Error [Modelica.Media: 4706:7-4709:26]:...

Inconsistent handling of $cse expressions in models involving interpolate() and state variable change

We have a fairy involved model that generates invalid C code due to a missing definition of a `$cse` variable which is then used in an expression. We were not...

Bug in CMAKE leads to FMU export with missing dependency

47

From the discussion in #11604, it seems that there is a CMAKE bug that leads to missing dependencies in FMUs if using clang (not if using gcc). @bilderbuchi [notes](https://github.com/OpenModelica/OpenModelica/issues/11604#issuecomment-1975883356): >...

Incorrect equation/variable number calculation by the NF in a MultiBody model

@perost, today I was working with @arun3688 on his drone modelling project and we stumbled upon this issue: the DCMotor1D model, which is built using components from the Modelica.Mechanics library,...
