Hi

Could anyone explain to me the concept and significance of mesh density as a function of steps per wavelength? I am asking this in context of a frequency domain EM-solver - CST MWS.

May I ask what are the "steps" and what is the "wavelength" ? I am trying to simulate a Photonic Crystal (silicon pillars in vacuum) within a frequency range 185-225 THz.

My computer continuously runs out of memory, please help me determine the least number of steps per wavelength for this. Also what is the significance of "minimum number of steps" in mesh density.

Thanks
