hfss convergence
Im having trouble with resonance and converging solutions. I've designed a wave cavity that consists of a full cell and a partial cell, seperated by irises, that are meant to set up a 0 mode (All E fields in the same direction) and a pi mode (opposing directions). The main cell has a wave guidfe and port created to transport the microwaves into the cavity. The problem is, when the field strength in the cavity is strongest the solutions stop converging.
My task is to tune the full cavity by adjusting the radius of it until the field strength inside the cavity is a maximum, but as stated above, when the field strenght is a max in the cavity and almost 0 in the waveguide, the solutions stop converging. The smaller cavity is completely detuned to assure only the main cell is being tuned.
My questions are:
What is it trying to converge?
Are there methods for tweeking solution setups to get convergence?
I've tried changing the mesh refinement, what now?
Its been a few weeks and am having no luck with trying to tune this bad boy! Any ideas would be great. I've included a graph and a picture of the cavity that might help you folks understand what im on about.
