I have used Dymola for a few months, but I don't understand why Dymola doesn't provide a debugger like OMDebugger in OpenModelica or Equation Browser in Wolfram SystemModeler, just with the error message and simulation log it hard to locate the error source. For example these following question on StackOverflow:

https://stackoverflow.com/questions/60975928/debug-the-structurally-singular-and-minimize-nonlinearity-of-modelica-models

Here is the screenshot of OMDbugger and Equation Browser in other tools:

I think there should be a debugger in Dymola that helps users to locate the error source or nonlinear equation system. I am also looking for alternatives to do debugging, any suggestions are welcome.
