Hello everyone, I wanted to know if it's worth using CST Studio Suite  for creating a 3D simulation of electromagnetic field measurements inside an office, in order to predictively assess EMF exposure.

Actually, I've already created a 3D model of the room using another type of software and then imported it into CST as an STL file. The biggest issue I'm facing is modeling the antennas of the electronic devices (mobile phone, laptop, and desktop PC). I was advised to create the antenna in a separate file and then import its far-field radiation pattern into the 3D office model—but I don't know how to do that.

Also, to make the room look more realistic, there might be some "useless" objects that don’t interact with the EMF and just weigh down the simulation. I heard there is a way to exclude these objects from the actual simulation so that they’re only there for visual purposes, but again, I don't know how to do that either.

Lastly, I’m not sure which solver I should be using—asymptotic or integral?

All of this is for university purposes.

Thanks in advance!
