Yes, I know.. But in the past versions at least 4-6 cores were used in full effectively speeding up the computation. I checked it at 4-core i7s and at a pair of 16 (8+ core DP Xeon workstations I was running in parallel in the past.nCheck your paper I have simpler system with the newer version of HFSS... and did not care for a while. Until got confused by performance drop and checked this load graph.n
