convergence criteria hfss
nadnerb
0 mode (All E fields in the same direction) and a pi mode (opposing directions)
??? - "0-mode" means 0 degree phase shift, "pi-mode" - 180 degree phase shift per cell.
My task is to tune the full cavity
What does it mean "to tune" ? Do you want to match the input wg with cavity ?
The left port (the larger of the two remaining) is not a port
Yep! Please write clearly how many ports you defined and how many modes are in each port.
Please, DO NOT MIX UP port and boundary, because its completely different things.
The piece was modeled successfully in SUPERFISH
SUPERFISH is eigenmode solver, but you talking about driven solution.
What do you want to compare ?
Anyway, please send a full geometry to have a qualified answer.

im pretty sure the HFSS can handle more then 27000 tets within 1GByte of Ram
Its true for most cases but sometimes, if you defined port with many modes and
have a high lossy material, then 1Gb might be not enough even for 30K tets only ...
