WSMSaveModel is being phased out in favor of the Export format "MO", which was introduced experimentally in Version 11.3.


saves a model previously associated with a location.


saves the model mmodel in files in location.


  • The mmodel refers to the fully qualified Modelica names.
  • The mmodel can be given as a string or as DotName.
  • The shortest unique model name mmodel can be used where WSMNames["*.mmodel"] gives a unique match.
  • The first time a new model is saved, a location has to be given with WSMSaveModel["location","mmodel"].
  • If location is a path to a file, the model is saved in that single file.
  • If location is a path to a directory, the package "mmodel" is saved in a hierarchical directory structure.
  • Subsequent calls to WSMSaveModel automatically determine the file where the model is saved.
  • WSMSaveModel saves all contents of mmodel, including models contained in it.
  • WSMSaveModel returns WSMModelData["mmodel"] if it succeeds, and $Failed if it fails.

Possible Issues  (1)

Already saved models cannot be saved in a different place using WSMSaveModel:

Make a copy of the model to save it in a different location:
