[Getdp] Piecewise defined source current density

[Wolfgang Suttrop]

Dear all,

I am trying to solve the "Team workshop problem 7" benchmark [H. Tsuboi 
et al., J. Materials Processing Technology 108 (2001) 237-240]. This is 
very similar to the 3D magnetodynamic example, except mu_r=1 everywhere, 
the passive conductor is multiply connected (which does not bother me as 
yet) and the stranded inductor has a racetrack-shaped cross section 
rather than a circular one. Because of this latter condition I find it 
convenient to define the source current density piecewise, on straight 
and curved volumes in the inductor. The calculated (magnetostatic) 
source field {hs} and source current {d hs} look reasonable to me.

When trying to preprocess the magnetodynamic problem ("getdp Team7.pro 
-msh Team7.msh -pre MagDyn_hphi", all files attached), I get an error  
message:
   "Error ('MagDyn_hphi_Bob.pro' line 142): Bad correspondance between 
Group and Entity (#BF 1, #Global 8)".
This error does not occur, if I give up piecewise definition but define 
js0 (with circular symmetry, i.e. wrong) on the single inductor domain 
("Coil").

I think I am making a stupid mistake somewhere, but from the (otherwise 
very nice and helpful) getdp manual and examples I can't quite make out 
where. Any hint is greatly acknowledged! Thanks in advance ...

Greetings,
Wolfgang Suttrop
