Description (last modified by )
Using the MSL mass with stop and friction with a force (see example below), Dymola detects a mixed system, which is handled as nonlinear system in OpenModelica. When looking at the equations, there is one linear equation, which depends on a boolean variable. Is there a mixed system detection and handling in OpenModelica?
