Hey!
I am new to comsol and have a little bit problem with a task. It says that I have to use the boundary condition to get the external fields above as the solution of the PDE in comsol. I dont know how to implement that in comsol and which the boundary conditions are. I think that the boundary conditions should be implemented in external current density in magnetic field node in comsol but im not sure. Hope someone can help me out. Thanks!
