I have noticed that there are several integration methods available in OpenModelica simulation setup. I dont know what these are. Can I get some sort of information regarding these? Will the quality of results vary if the integration methods are changed?
Short document on the integration methods available in OpenModelica: https://openmodelica.org/svn/OpenModelica/trunk/doc/SimulationRuntime/IntegrationAlgorithms/
Yes, the quality (simulation speed, even finding a solution) could vary if you choose different methods. The default is dassl.
