[Getdp] Current Flow Problem with getDP

Dear Sir's

I have been attempting to use your software getDP to solve a current  
flow problem and was hoping that you could steer me in the right  
direction.  The problem is to determine the current flow (low  
frequency) from an electrode(s) buried in the earth and the resulting  
temperature rise.  Presently I use a FDTD program to determine the  
results, however, I have been intrigued with the possibilities that an  
FEM approach may yield.

Where I get stuck is in the formulation of the problem for getDP.  I  
see how you set it up for electrostatics, and it should be a simple  
transition to solving the current flow problem (quasi-harmonic  
solution of Maxwell's equations), but I seem to be missing something.   
Would you have any data sets or examples where you solve the electro- 
thermal problem.

My geo file is attached and it loads nicely into gmsh.
