We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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?
