Nan output for E-field of an infinitely PEC beam #243

Open SaihangQie opened 1 year ago

SaihangQie commented 1 year ago

I am trying to compute the scattered field of an infinitely PEC beam. I use the command-line tool scuff-scatter to complete the calculation. The gmsh geometry file for unit-cell geometry is from /scuff-em/examples/SiliconBeams. Lamnbda = 1 micron. The incident wave is planewave. I set pwDirection 0 0 -1, pwPolarization 1 0 0, EPFile observePoints.

However, the result of scttered filed is all nan. I am not sure why this is the case. I will appreciate any suggestions on how to resolve this error. Thank you.
