Currently it is a problem with the compiler, but it could also be for the runtime simulator. I'm not sure if those systems are stiff or not. For sure DASSL...
> @perost this model uses the `RectangularZoneTemplate`, which includes many conditional components. If they are flattened and not simply ignored then that could be part of the explanation. I've also...
@perost we are planning to build a library to support boiler design, to be used with OMC. The heat exchangers models in that library can be either 1D or 2D....
@rfranke, this system seems to be a bit ill-conditioned. I tried it with Dymola using tolerance 1e-4, 1e-6 and 1e-8, these are the derivatives of `line.v[2,1]` in the thee cases:...
@kabdelhak I need your help here. First of all, Dymola reports two linear systems at initialization, one of size 14 and one of size 4, which both get reduced to...
OK, now I guess I found where the problem may be. If I set --tearingMethod=noTearing, there is an initial linear system with 35 unknowns (all the line currents and voltages,...

> Since this will be a new feature anyway, maybe we can represent clock ticks with vertical lines to address the issue raised in [#8105 (comment)](https://github.com/OpenModelica/OpenModelica/issues/8105#issuecomment-1008340758) This would only work...
Still open as of v1.20.0-dev-119-g4241954151
