Interpolation function in Geometry

Hello everybody!
I can't set the position of an object via a function definition in neither global definitions nor model definitions (in comsol 4.2a).
Does anybody know if user-defined functions aren't allowed in the geometry section?
Attached is a minimalistic model highlighting my problem.
Best Regards,
Magnus

Hi
that is a limitation in 4.2 and I'm afraid it is still so in 4.3. The reason I was told by "support" is that the functions and variabes are interprested during the solving sequence and not prior during geoemtry set up. Today you can ONLY use parameters to drive your geometry, and these must be defined in the Parameter section, BUT might be adapted by a Parametric Sweep (and not a solver continuation sweep) method.
To get it running your way I suppose you will HAVE TO pass via matlab and drive COMSOL from there, but then it should be now issue

Good luck
