Optistruct CPU Default

If thre'is no supplementary parameter, only ONE cpu will be used, I think.

can you please explain more? my Desktop Properties are:

Intel(R) Xeon(R) CPU E5-1620 v3 @ 3.50GHz 

Ram 16 GB

64 Bit

how can i fasten the analysis which tricks can be used rather than modelling tricks?

Have a look at my screenshot. With parameter '-nt 4' your job will be calculated with 4cpu in SMP mode.

With the standard direct solving method parallelization is not efficiently used....use PCG Solver (iterative) for linear static analysis e.g. to fasten your analysis A LOT!

Load collector --> card image 'SOLVTYP' --> PCG --> Load Step --> SOLVTYPE ...

Thank you both. excellent explenation. sorry for replying late!
