I am quite new in ANSYS and I have a question regarding simulation of magnetic behavior of ferromagnetic material. As far as I know, in every ferromagnetic body a demagnetization field is created, when the body is magnetized.
The size of the demagnetization field is shape-dependend through a demagnetization factor.
Does ANSYS take this demagnetization field into acount?
Does it depend on the selver option I use? I'm using the RSP method.
I attached a simulation result, where the H-field is displayed. The inner body is a ferromagnetic flat cylinder. Then there is a fine meshed air body and then another air body which is meshed more roughly.
The xternal magnetic field I create with
D,ALL,MAG,xmax*hfield0 ! APPLY POTENTIAL TO GIVE 100 TESLA FIELD
D,ALL,MAG,-xmax*hfield0 ! APPLY POTENTIAL TO GIVE 100 TESLA FIELD
Am I right with my assumption, that the H-field inside the ferromagnetic body is smaller than H-field in the air because of the demagnetization field in the body?
