Optistruct Running Job Problem
Altair EmployeeHallo Guys,
i have a part with TETRA 1st oreder element optimized the running was quick (20 min) simulation time and it needed low memory, where i have used default value.
However i have changed the Element to 2ed Order TETRA to have better results. but the simulation does not run or maybe tooks to long i get a massage with :
The amount of memory allocated for the run is 648 MB.
This run will use minimum core processing in the solver.
What to do????
Thanks in advance

Altair EmployeeHallo Mr. tinh,
where i can specify this option len 4000. I am using GUI of Optistruct, i have only a memory default. do you mean that?
Thanks for your reply.

On Optistruct GUI, can you see 'Options:' entry box?
and there is a button '...' on the right, click on it, then check on '-len', enter memory MB
Altair EmployeeThanks for the answere, how do i know how many CPU is used by Optistruct as Default value?
I don't know default NCPU
But try run a job and open task manager, look for how many CPU working
for more info about CPU, open '.stat' file to see
Altair Employeethsnks alot this is informative and rather simple!
Hi,
specify option ' -len 4000 ' to indicate using 4G RAM for running
if message does not say 'this will use in core processing', try increasing -len option (you may need more RAM with 2nd order)
