Optistruct Running Job Problem

Hallo 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

Thanks for the answere, how do i know how many CPU is used by Optistruct as Default value?

tinh

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
