  We have 512GB RAM but error showing
  
  ,
  We already given 95% RAM limit.
  Moreover, mention How to do HPC properly i.e. .accessing of all cores and RAM of other workstation. We are already using server license for different workstation via network. We have pool and HPC pack license.
  We have 40 cores & RAM 512GB three workstation. We want to make it 120Core & RAM 1536GB for simulation. Kindly help.
  Thank you

  this problem is not common in 64-bit windows kernel, but you may deal with memory fragmentation. It was a big problem plaguing all x86 windows. In Linux the memory manager is more flexible, so you can try using linux version, or remove all the non-relevant software, particularly antiviruses from the simulation workstation.
  
  another guess... GB may mean 1000 Mb, or 1024MB... lets calculate the worst case:
  477*1.024/0.95=514.2Gb required

  HFSS 2020/2021 does not scale with core number per task. probably, bad programming. but it may be scaled with many tasks. therefore do not use large multicoring - use a distributed network of 4-8 core machines with the fastest CPU clocks available.

  To use the 3 machines together please refer to the Help documentation.

  Thats per design. You need a license token in a cookie. Go to HFSS, press F1. When the help is opened, go to the link. Awful design, very slow and hard to use. I had to wait 15 minutes today in order to see some specific features config. I prefer the old offline hypertext manual when available.
