I'm trying to work with a collaborator using v5.5 and when importing his code via eclipse/JAVA I get errors on all the model.component() lines in eclipse.

The method component() is undefined for the type Model example.java

Do I have to use modelNode for 5.2 instead of component?

Hi Ben,

There are large differences between versions 5.2 and 5.5. COMSOL Multiphysics is backward compatible, so that you can open and run 5.2 model files in version 5.5, but the other way around is more problematic. The 5.5 code might contain functionality that does not exist in version 5.2, and there may be other changes that affect the compatibility. I strongly recommend upgrading to version 5.5, which contains a lot of new and powerful functionality.

That said, you are correct: model.component() corresponds to model.modelNode() in earlier versions of COMSOL Multiphysics.

Best regards,

Magnus Ringh, COMSOL
