hfss helix
I need to simulate an spiral helical antenna to determine its FF pattern.
I modelled the helix in HFSS surrounded by a cylinder of vacuum of few wavelenghts in lenght and less than a wavelenght in radius, but when I try to simulate the meshgride generated automatically becomes huge and simulation crashes for out of memory. Actually, the computation does not start and stop at the first step.
How can I reduce the number of thetraedra? I tried with model resolution and mesh operation but the initial mesh is essentially the same.
Further, it sounds very strange that it is necessary a so huge number of elements to model the helix antenna in free space. Does anybody knows how to perform the simulation in an accurate way and with a computational burden that is affordable?
Attached there is the model file.
Thanks in advance.
Bye.
