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

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)

Hallo 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

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
