The demo version of PS-PERMAG 3.1 is constricted by the following:
For multipolar homogenously magnetized cylinders one can define, compute and save all sorts of problems, but the number of poles per area will be constricted to six and eight. Beside this the user can apply all program features to these magnets.
For all other magnets there will be supplied quite a big number of already solved problems by the setup routine. The respective files can be read by the software for viewing purposes. But a computation of new results would be denied by the software here.
