I will check your posts for sure. Anyway, do you know (approximately)
when can Magnetostatic 3D formulation appear there ?

<pre wrap="">Dear Mathias,
Thanks a lot for your reply. I welcome everything, because I need to
get familiar with GMSH & GetDP and I don't have lot of time. :(
You were assuming right that I need this for real 3D problem, because
it won't be symetric. That definition with Vector looks good, but I
have one question. Is GetDP capable to take such definition in
cylindical coordinates ? If it works, it can make things easier to me
(I hope).
Another question I have is about Inf (AirInf) region always used in
examles. Is there an exact rule how this must look ? For example, can
this region be defined like volume between two coaxial valves ?
If this has already been discussed in this mailing list, please help
me find it. I am new in mailing list. I was looking for something in
archives, but I wasn't successful yet.
Best regards,
Palo

<pre wrap="">Dear Pavol,
for an axisymmetric problem I could offer you a geometry and a
problem description file. I shall attach these to this message. From
your first message I assume that you are interested in a true 3D
problem, right? I guess one could try the straight forward way and
define a source current density j[Coil] = Vector[ -Y[],X[],0 ] in
region coil (be aware I have not tested this, X[] returns the X
coordinate of an element, see recent mailing list).
But maybe Christophe can show you a way how to utilize global values
to drive a source current in an arbitrary geometry.
Best regards
Matthias

<pre wrap="">Hi again,
I will try to start with something simpler as I am starting with
GMSH and GetDP.
Lets have a problem like in geometry in attatchement. There is one
coil placed in air (coaxial).
How can I define source current density in coil ? What about
boundary conditions ?
