J. Anaya

Dear Jamal,

I would recommend you to activate the equation view in the model builder, then you will be able to see how things are called by COMSOL. If it is a simple derived magnitude you can access to the names by Ctr+Space bar in any evaluation field.

Kind regards,

Julian

Have you tried arc tangent. example Atan(mf.Br/mf.Bz) in a 2D axisymmetric model ?

In a 3D model you'll have mf.Bx, mf.By, and mf.Bz.
