Default Cells vs. Memory
Posts: n/a
Hello everybody, I'd like to ask what is the function between number of cells and megabytes of memory in Fluent5. Otherwise how many megabytes do I need for every 10 000 of cells?

It depends on which solver you are using. The coupled solver tends to need more memory.

I'm just now running a ~300,000 cells case with the coupled solver (stationary) and it takes around 600 MB. YMMW.

The memory requirement depends on the solver and physical models used. For 3D turbulen flow problems, the segregated solver in FLUENT 5 takes roughly 1MB of RAM per 1000 cells.

First sorry for my bad english

Its depend from the solver. Aprox. 1Mb RAM / 1000 cells (segregated)

Now im solving a 800.000 cells problem, MRF, segregated, K-E. with aprox. 500 Mb RAM
