Magnetic Fields, No Current
Posted 2012年10月14日 GMT-0400上午9:48 AC/DC & Electromagnetics Version 4.2a, Version 5.2a 5 Replies
So I've been trying for a while now to bypass the problem of creating an external magnetic field in *other* AC/DC modules; but now I see that in the MFNC there are two options: External Magnetic Flux Density, and the same without external. The External seems to be a pointless node - it does not make any change at all in the model, does not affect anything - and you cannot provide it with any information;
so here's the first question - what does the External Magnetic Flux Density node do?
the other node, without external, seems to work if you have a stationary model, but if you have a time dependent, any field that is not 0 makes it not converge. attached a model; can anyone tell me what is wrong?
I'm working with 4.2a.
