WSMSetValues is being phased out in favor of SystemModel, which was introduced experimentally in Version 11.3.


sets parameters pi to ci in the Modelica model "mmodel".


sets the initial values for pi to ci in the Modelica model "mmodel".


  • WSMSetValues sets values for the Wolfram SystemModeler kernel.
  • WSMSetValues allows you to set parameter values and input variables.
  • WSMSetValues["mmodel",{p1->c1,}] is short for WSMSetValues["mmodel",{p1->c1,},"ParameterValues"].
  • Current parameter values can be found using WSMModelData["mmodel","ParameterValues"].
  • With WSMSetValues["mmodel",{},"InitialValues"], initial values can be set for all variables and parameters.
  • Current initial values can be found using WSMModelData["mmodel","InitialValues"].
  • The shortest unique model name mmodel can be used where WSMNames["*.mmodel"] gives a unique match.
