Hi Janvrot,
<blockquote TYPE=CITE>Thank you very much for the files. I would not be
able to do it by my
<br>own.</blockquote>
You're welcome.
<blockquote TYPE=CITE>
<br>I took some time to figure out how to compute the values for another
<br>magnetization curve, and I guess I got it. I ran the pro putting a
<br>magnet on, taking the inductor off and results seems ok.</blockquote>
hc[ Magnet ] = Vector[0., 0., -920000.]; ???
<p>In a 2D problem, hc must be in the xy plane!
<blockquote TYPE=CITE>
<br>Nevertheless, I'm having problems running in 3D, my target problem.
Is
<br>this ok for 3D?
<br>I get
<br>Warning : Null right hand side in linear system
<br>Error : Zero row encountered in ILU</blockquote>
The source term (due to the permanent magnet?) is not properly written,
I guess. This may produce a zero RHS.
<br>
<blockquote TYPE=CITE>
<br>Attached you may find a complete pro file (without includes) and
<br>solver.par</blockquote>
This is still for the 2D problem, I guess. Can you send the new geo file,
so that I can run your stuff?
