Ram memory doubt
Hi everybody!
I've been checking different threads on the forum but i dont know exactly for my case...It seems there is a thumb rule which says that u need about 1Gb for every 1 million cells...IN my case i'm gonna work with a 6 millions cells case and my desktop has 8 gb ram. However i couldnt run with it. I've installed windows 64 bits but fluent is 32 bits one... Any advice? should i get more ram memory? or shall i work with a 64 bits fluent version? |
Isn't one of the advantages of Windows 64 that it can access more than 2 Gig of RAM? Seems to be limit in 32 bit version, unless you are running a parallel version of Fluent.

A 32 bit program can only address 4GB of ram in theory and in reality, only about 3.4GB for reasons that I'm not 100% sure of. (I think is something to do with the system needing the rest)
If your running a 64bit OS your 64bit programs can access much more memory however any 32bit progs will be run via an emulator (WoW64) so will not have this benefit. You will need a 64bit version of Fluent, or will need to run your job across several workstations in parallel. |
Hi ski!
thanks for ur answer. Now i can understand also Allan's one (thanks Allan also for urs...) But is there any way to run a case in parallel in my computer. whenever i've done it was in a cluster, but in my case, although is true that there are 4 units of 2 gigas, i've never tried to run it in parallel...is therefore possible? |
