How many elements can my mesh have based on my system config?

[nshankar118]

Hi,

I'm setting up a flow/thermal simulation in a complicated geometry (simplified as much as possible). Autosizing gave me ~25 million elements. When I solve the study, the mesher process consumed ~42 gigs of memory when I stopped the analysis since I thought that was too many elements.  

My question is - is there a thumb rule for how much memory and processing power I need per, say, 1 million elements? 

I'm running the simulation on a server with 96 GB RAM and 2 processors @ 3.47 GHz. 

Thanks,

Nikhil

Hi Nikhil,

I think this will help, always worth a quick search in the knowledge network 🙂

How to know how much RAM will be needed for a Simulation CFD analysis?
