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


creates a copy of the model with the name name.


creates a copy of the model source with the name dest.


  • Both source and dest refer to the fully qualified Modelica names.
  • Names can be given as strings or as DotName.
  • If dest already exists, it can be overwritten with the option OverwriteTarget->True.
  • If the parent of dest does not exist, it is created automatically.
  • WSMCopyModel returns WSMModelData[dest], or $Failed if it cannot create the copy.
  • The shortest unique model name source can be used where WSMNames["*.source"] gives a unique match.
