    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 ...
