For those that want to use the Pardiso solver you need to download the solver from the site specified : [http://www.dhondt.de/calculix\_2.20\_4win.zip](http://www.dhondt.de/calculix_2.20_4win.zip). The download will give you the following files:  
ccx\_dynamic.exe, ccx\_static.exe, cgx\_FREEGLUT.exe, cgx\_STATIC.exe, glut64.dll, README\_install and tetgen.exe.  
Copy those files to the Solver folder in your PrePoMax directory.  
ccx\_dynamic.exe is the solver that uses the Pardiso solver. You activate it by going to the Tools/settings/ options in the menu and then changing ccx\_static.exe to ccx\_dynamic.exe  
You will then have to download the following libraries and copy them to the solver folder of your PrePoMax installation:  
libiomp5md.dll, mkl\_avx2.2.dll, mkl\_avx512.2.dll, mkl\_core.2.dll, mkl\_intel\_thread.2.dll, and mkl\_rt.2.dll.

You download those libraires from the intel site:  
[Get Intel® oneAPI Math Kernel Library](https://www.intel.com/content/www/us/en/developer/tools/oneapi/onemkl-download.html)  
Once you have all those files in the solver folder, you can then chose to use the Pardiso solver for your model.  
Cheers!
