Hello,

I wish to calculate the absorbed photon density (as a function of space) in Meep, to be input to an electrical device simulation. Is there an efficient/quick way of doing this? The only method I can think of is to use output_poynting() to get the Poynting flux at every time step, then after the simulation time-average all of these fluxes, numerically find the divergence, and then finally divide by h*(frequency of photon). However, this seems like it would be very inefficient. Is there another approach (perhaps somehow using a FluxRegion object)?

Best regards,
Philip
