Hi! I was wondering if anyone using Meep here know how to run a simulation where there is a need for two simulation runs! One where the structure does not exist and the aim is to record the source, and the other where the monitor records the source and the reflected wave, and it deduct the results achieved from the first simulation to gain the pure reflected wave! – this is similar to the bend waveguide example in Meep wiki page!

For this I need a terminal window where I can write the command and tell meep whether the structure exist or not, and if it is supposed to deduct any data from the reflection monitor or not!

thanks, Asa
