I have upgraded my hardware to 16gb RAM, but it seems windows 7 32-bit utilizes on a max of 4gb so the rest is unusable. I'd like to understand if CFD has a feature to use the actual physical memory of 16GB installed.
Does changing to a 64-bit OS platform have a better impact to utilize the memory RAM for CFD.
Solved! Go to Solution.
The limitation here is the 32bit OS, there is no way to access it on a 32bit system.
If you move to 64bit then yes, we would be able to access the additional RAM.
