Interpolating external Data to Certain Parts of the Geometry

Please login with a confirmed email address before reporting spam

Good Morning,

I need to import externally computed datapoints into COMSOL multiphysics.

I have a geometry which looks like a sandwiched structure, consisting of a metal - insulator - silicon - metal. I want to load my externally calculated electron distribution onto the silicon itself.

The reason why I need to do this, is because Comsol is unable to calculate the electron distribution as soon as the structure looks like a metal - insulator - silicon - insulator - metal, which I also need to analyze.

I tought I could just create an interpolation (int1), load the datapoints (x,y,n(x,y)), check "Use Spatial coordinates as argument" and change the Frame to Material. Then I would just call the function from the material properties as int1(x,y).

This doesn't throw me an error, however the simulation does not converge. What am I doing wrong?

Thank you for your time and ahve a nice day, Killian
