The wrong solution is probably because of `sys = dae_index_lowering(sys)` and not an issue of OrdinaryDiffEq.jl but SciML/ModelingToolkit.jl. It is simply that an important equation `y=3*x` from the original system...

I would be interested in MAT v4 support as well. We have a tool ([OpenModelica](https://openmodelica.org/) / [OMJulia.jl](https://github.com/OpenModelica/OMJulia.jl)) that is generating mat v4 result files, that I would like to open...

> @AnHeuermann, you recently implemented the spatialDistribution() operator in OpenModelica, maybe you want to comment on that as well. I think myself and @kabdelhak did find the standard on this...

We did this around a year ago. Sorry, I don't remember anything any more. But I think the concept of ```Modelcia Real points[:]; Real values[:]; ``` being storage over multiple...

> Adding such implementation hints seems a bit outside the scope of the specification; and we might soon be over-burdened. I agree and the implementation is using OpenModelica specific data...

My initial idea for the shiftOperator was, that I need to shift every tick of `u` by `k/resolution * interval(u)`. So for the first tick of `u` at `time=0.0` I...

And of course I can't reproduce the exact error with asan: ``` $docker run --rm -it -v /home/andreas/workspace/OMSimulatorStandalone:/OMSimulator docker.openmodelica.org/build-deps:v1.13 bash #export ASAN=ON #echo $ASAN #cd /OMSimulator/ #make config-3rdParty -j #make...

My next best theory: We are running out of memory at https://github.com/OpenModelica/OMSimulator/blob/master/src/OMSimulatorLib/MatVer4.cpp#L93 and the Jenkins test reports: ``` OMSimulator: /var/lib/jenkins2/ws/OMSimulator_PR-916/src/OMSimulatorLib/MatVer4.cpp:96: void oms::appendMatVer4Matrix(FILE*, long int, const char*, size_t, size_t, const void*,...
