Which Solver are supported in OpenModelica

Jun-21-13 10:25:44

Hi,

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!
T

radau1 is roughly implicit euler. Which version of OpenModelica (OS, revision) are you running?

Is there no list with all possible solvers?

Still didn't say the OS. Some versions are not linked against sundials because it's not available for the platform.
