Good evening all, I'm very much new to COMSOL. I'm using a newly added Micromagnetics model

In the global definitions, how to define a variable as a vector? In the global definitions, in an analytic expression how to mention cross product of two vectors?. Similarly how to mention dot products of two vectors?

Say in one of the existing model, for a parameter i want to enter an expression AXB (A cross product B), my basic doubt is how do i create these two vectors first and then how to express the cross product.

Thank you in advance. Vinod Naik

Hi,

you must express any vector by its components.
