Newbie level 5
I am now simulating antenna over 50 GHz with package signal traces, vias and solderballs. The structure is very complex (5 layers). I am simulating it in HFSS. the initial mesh costs even 1 G RAM. 1st round mesh can not be finished with message of " insufficient memory'. Can anyone provide some idea how to decrease the calculation load in HFSS? or suggests me using other softwares for such complex structure?
