Run the simulation using the hard disk

Submitted by rodolpho101 on Fri, 03/10/2017 - 14:46

Hi all,
I have a simulation that requires a lot of Ram memory, and when the simulation uses the swap, my computer gets very slow. Do you have a way to limit the use of RAM and make the solver run the analysis in the floopy disk?
Thank you for help!

Hi Rodolpho,

that depends on the case, how many GB of RAM do you have? How many particles and how many CFD cells do you have?
My first guess would be to increase the binsize of LIGGGHTS, which reduces the RAM usage at the cost of performance. However swapping reduces it muuuuuch more.

Cheers,
Josef
