Description
Solver for the magnetic field generated by permanent magnets.
A Poisson's equation for the magnetic scalar potential psi is solved
from which the magnetic field intensity H and magnetic flux density B
are obtained. The paramagnetic particle force field (H dot grad(H))
is optionally available.
