  • Ticket #3440 – Description

    v2 v7  
    11Using 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?
