EM Field Simulation

I am using your program for mechanical FEA and it works great. I would like to know if it is possible to simulate a EM field set up by a magnetron (antenna) in a resonant chamber. It does not have to use EM elements it just needs to handle 3D waves. Any thoughts?

    Hello Protontim

    I don't know much about EM modelling. Though apparently [1] you can use the Helmoltz equation which is what's solved in the 3D Acoustic Resonance analysis type. For EM waves with permittivity = 1, set speed of sound = speed of light, and treat pressure as "A component of the magnetic field strength vector".

    Mecway also has a time-dependent acoustic wave analysis type which is disabled by default because it isn't well tested nor very practical. Please contact me by email if you think this might be useful.

    Thanks. I purchased the book you referenced to have a closer look. I will contact you by email if it seems profitable. Thanks again.

    What I quoted is pretty much the entirety of what Rao says on the subject of EM. The rest of the book is still a good description of the finite element method applied mostly to structures. I hope it's valuable to you.
