Problems about the size of output files

Fedindras · September 18, 2017, 14:34

Hi all,

I have a problem with the size of out files. I've launched a simple URANS and it ran for almost 2 days. The problem it's that this simulation reach a size of 600 gb..
My question is: it's possible in CONVERGE CFD to update output files during run time so that to keep a low number of output files?

Thank you very much and sorry for my english

Federico.

Federico,

You can change twrite_post in inputs.in during a simulation to change the frequency at which the 3-D output files are written.

Best regards,

Tristan

Thank you for your answer Tmburton
I saw those commands but is it the only way to reduce output size?

You can adjust the texfile output as well, also reduce output variables to only really needed ones.

For storrage of simulation results, you can zip them. Doing so, i have less than 10GB per 720°CA cyclic case.
