predefined task in hfss

I don't have the option for multicore usage. So I agree with rfmw that you need a special license. Or it is because my PC has a single core CPU. (the remote machine is dual core.)

i am confused. some say you should have a special license to exploit all cores in a pc, with HFSS programm, some say you should go to tools/options/hfss_options and just put the number of cores there. Does anyone know what is really the correct of the two?
I have an intel pentium core 2 quad pc and i tried with the second way to take advantadge of all 4 cores. The result on the real time of HFSS wasn't much different and in the task manager the cpu usage percentage didn't change. Do all these mean that i haven't activate all cores for HFSS simulations?

Thank you

I have a Dual 6 core xeon processor.... does that work the same way?
