help me choose the best Poisson solver

[huangshenjie]

Hi, I have built a MTJ, CoMnO/ MgO / CoMnO. However, I don't which is the best Poisson solver.
Could you tell me the proper solver? Thanks.

The default "FFT" is OK for your system.

Thank you very much. I still have another question about contour integral. In order to get proper result and save time, which value should I choose about real axis point density and infinitesimal?

And if I insert a Cu layer between the barrier and the ferromagnetic layer, should I still choose  FFT?

Please first try the use of the default values.
