HFSS system requirement

What is the highest requirement in the system in terms of RAM size, hard disk required and other features etc. to run the simulations of HFSS, even for the lenthy simulations at optical frequency. If anybody knows then do suggest me. Actually I want to buy a new PC /Workstation, so want to get the right configuration. So that i won't receive the error message: out of disk memory....and all that.

Please help . thanks in advance.

hi
for optical regime you need very high quality of hardware

Yah I know.. But I want to know exactly what is required? Some configuration if anybody can suggest?

may be one PC cant help u and may be u need to use some PC
