This issue is from a [discussion on discourse.julialang.org](https://discourse.julialang.org/t/modelingtoolkit-index-reduction-and-linear-algebraic-loops/69312/3) about ModelingToolkit.jl and that I used wrong start values for my ODE problem. **In short** I'm using the wrong start values `u0`...

Clarification on shiftSample with changing intervalCounter of base clock

I'm not sure if I got the definition of `shiftSample` ([16.11 in the Specification](https://specification.modelica.org/maint/3.5/synchronous-language-elements.html#sub-clock-conversion-operators)) right. For the following model the `intervalCounter` of `u` will change after the second tick. The...

Insufficient event location detection

### Description I have a OpenModelica FMU in a directory that contains a `+` in its path and when I simulate the FMU OMS can't find some file and reports...

I would like to have a way to load a model from MSL or an other library in your Modelica library path with `ModelicaSystem`. Apparently some new users are struggling...

### Description When following https://github.com/OpenModelica/OpenModelica/blob/master/OMCompiler/README.Linux.md#debianubuntu-compile-cheat-sheet-or-read-on-for-the-full-guide to build OpenModelica on Ubuntu some tools are missing. `ccache` and `flex` are missing to build the compiler with CMake. In addition I saw that...
