Hello Francesco and everyone else.
Just trying to understand the flow/logic of assigning magnetic fields in
a region.
Here is my understanding and a question where I lack understanding...
1) MGNFIELD card activates calling the subroutine MAGFLD defined in mgfld.f
2) In subroutine MAGFLD, one defines the intensity and direction of the
magnetic field(s) and assigns it to a given region(s).
3) Set Field to Magfiled in the ASSINMAT card for the region(s) with
magnetic field.
What I don't understand is why do we need to turn on magnetic field in
the ASSIGNMAT card? Is this not already set via MAGFLD?
Best wishes,
Mina
