3d crosshole array

Hi Thomas,

I am trying to run the following 3d crosshole inversion file with the default settings, and I get memory error. The file has 4 boreholes, with 48 electrodes each. test2.pyg. I am not sure that the mesh is too big. I tried also to run this through pygimli, but I got a windows fatal error let's skip this atm).

Could you advise how to proceed?
