FDSim

Hi
I have a problem in FDSim3D User guide in SR_File_Name (page 12) when PWINC factor determines type of sources. In case of PWINC>0 , this error (The plane wave incidence in not possible if a discontinuous grid is used) appears. How can I solve this problem?
Is it possible to use PWINC =1 & 2 simultaneously?

Hi,
the plane wave incidence is possible only for non-discontinuous grid. It means you have to use LPAS = 0 and REFINE = 1 and then you will have only "coarse" grid with grid spacing H (no "fine" grid).
You cannot use PWINC = 1 and 2 simultaneously.
