ok, thanks. 

Following up on the intensity question, I’m getting the power, intensity and area of my gaussian source using the method posted here https://optics.ansys.com/hc/en-us/articles/360034925313-sourcepower-Script-command.

However, i got power =4*intensity*area. This factor appears to be a constant of  my other numerical parameters including the monitor size and source size. I’m using anti-sym and sym boundary conditions. But my understanding is that those are accounted for in the sourcepower and sourceintensity functions. Is this factor expected? if not, how do i fix it?
