How to set PARDISO solver

1

Hello,
I need guidance on configuring the PARDISO Solver. Despite my attempts to set it up, it seems to default to using Spooles as the solver. When I try to set PARDISO getting this error.
Using up to 1 cpu(s) for the stress calculation.
Using up to 1 cpu(s) for the symmetric stiffness/mass contributions.
*ERROR in nonlingeo: the PARDISO library is not linked
Is there a way to specify the solver through an INP file?

Thanks,
Bhavita

You need some additional libraries for Pardiso. You can find them here: https://staff.tu.kielce.pl/rokach/instr/misc/ccx_220.7z

Copy all of files referenced on the Calculix site (look for a link simply called “files”). Use the executable with dynamic in the name. This executable will default to PASTIX but can be changed in the CCX deck with the *STATIC command.

For running multprocessor, use Windows settings

OMP_NUM_THREADS=6
CCX_NPROC_STIFFNESS=6

Using more than 6-8 proc for most models will not reduce run time further.
