I upgraded Comsol from 3.5 to the newest version. Unlike 3.5 I have problems with setting the internal boundaries with the newest version. I have a long metal cylinder (approximated by a circle) inside a uniform magnetic field and interested to know the effect of the cylinder on the magnetic field. To define the field, I have a big square with the boundary condition: "Magnetic Field" in AC/DC, Magnetic Field module. Unlike version 3.5, I can not find the boundary equation for internal boundaries (circle). In version 3.5, I used the continuity equation (culr H1 = culr H2) in Magnetostatic module and it worked and the physics made sense. If I assume by default it set the boundary condition to continuity, the solver gives me an error. I tried AC/DC, Magnetic field (no current) module as well, however it did not work.
