I have a very problem with the accuracy of simulation results even though I use a very low tolerance and wondered which solver I can use in OpenModelica.
The GUI shows:
- dassl
- euler
- rungekutta
- inline-euler
- inline-rungekutta
- dasslwort
- dasslSymJac
Are there more I can use? Can I set an implicit euler e.g.?

I don't really find a documentation about the solvers I can use in Modelica, so thx for the answers in advance!
