RAM usage
RAM usage
(OP)
Hi, is there anyway to force abaqus to use more RAM during the analysis. The total amount I state in the job module never seems to get used during the analysis. Just wondered if there was a way to make abaqus use all the ram I state to speed up the run times.
Thanks.
Thanks.





RE: RAM usage
The model (i.e. stiffness matrix) just gets loaded into the RAM, and that's about it. Bigger model, more RAM use.
Thinking about it, that's more than likely why abq/STD uses more RAM than EXPL, as calculating the inverse matrix is very memory intensive.
Anyway, your question doesn't make much sense.

myINP: Name of your INP.
#: Number of CPUs.
$$$$: Amount of memory (4000, for example)
If you are running Standard, more/faster memory will help. If you are running Explicit, faster/more processors will help.
Even in case of Standard, the processors may not run at near full capacity at all times. Same is true for memory.
Another perspective: If possible, avoid nonlinearities as much as you can. Depending on the problem, you may try using reduced integration elements, exploit symmetry, and use simplified geometry.
