Hello,
Can you recommend software for performing Finite Element Analysis, or
Method of Moments simulation of E and H fields around a 3D structure?
I looked into FEMM, but that seems to only work in 2D.
I am aware of commercial packages like CST, COMSOL, HFSS, etc. I dont
have $20k to spend.
Can you get a plot of the fields with NEC?
Thank you for advice,
Sean
