What it can do

  • Connects to a COMSOL Multiphysics Server you started yourself, loads a main .mph and locks it so the agent can't switch or save the wrong model.
  • Lets you watch geometry, parameter, mesh, physics and solver changes live in COMSOL Desktop connected to the same server.
  • Sets parameters, evaluates expressions, edits geometry features, physics interfaces, variables and solver configurations, and runs studies in the background.
  • Saves snapshot copies for each iteration and loads large models asynchronously.

Limitations

  • Windows only, and you start COMSOL Multiphysics Server by hand and pass its port.
  • Material management, mesh features and result export are on the author's to-do list.
  • Documentation is mainly in Chinese, with an English section.
