Out of memory


#1

I was trying to mesh the “workshop2 full car aerodynamics”. But after running for 76 minutes…it says that "Machine ran out of memory…please select larger machine for computation.

How do i solve this problem?

Hi @bharadwaj92

Running on more cores increases your memory allowance. You change this in the ‘Simulation Control’ Node, how many are you currently running? how big is the mesh?

Kind regards,

At that time I was running 3 processes at a time. It was using around 64 cores in total.

Did i get the error because of that…!??

BTW thanks for your reply

no, it only matters what you use on that one job, so for example, if you running on 4 cores and you receive the error, increasing the job to run on 8 cores should sort you out (unless you really miss-judged). Normally 4 cores can serve me up to 10million cells, however, every simulation is different, you just need to approximate and adjust.

I just noticed you got this in the meshing stage here is where you adjust:


As you can see you were using 4 cores, up it to 8 and see how you go :slight_smile:

Kind regards,

Ok…i understand…

I will try it again…:slight_smile:
