Re: COMSOL or CST?
loucy,
you seem to be pretty quick to assume what CST can't do. Their EMS solver can do this - perhaps not full multi-physics stuff but you can do a thermal solution using MWS losses - pretty convenient.
Comsol is conceptually pretty powerful but you really need to know what you are doing and also know whether the results make sense - the number of factors that can affect the results is higher - same for Ansys - most people cannot say, without some sort of measurement, whether the results can be trutsed or not - the mesh is for example different for an electromagnetic field than for a thermal mesh.
Comsol really cannot compete with MWS / EMS when it comes to user friendliness, CAD import and post-processing etc.
If you are a programming / Matlab type then by all means is Comsol a potentially good tool - however, for companies, Comsol would actually be the expensive option since you need skilled people to use it - most RF and MW engineers don't want to be thinking about the equations being used but the actual design of the device - if the software has been validated and is widely used, then software such as CST's is very attractive.
I used to be very acquainted with the equations but I now want to concentrate on design and not equations and then design.
Just my opinion but I'm sure there are a lot of people who think similarly.
