PARDISO Solver Project

1. Go to http://www.pardiso-project.org/.

2. Download the academic license.

3. When completing the forms, the website asks for a user name. Specify the

computer username as the user name.

4. After completing the procedure, the user will receive an email from the

PARDISO project with the download link, and the license key.

5. Copy the license key into a .txt file named ‘pardiso.lic’. This file must be

placed in the same folder where the VecTor2 substructure is located.

Simulation Steps

Save the ‘pardiso.lic’ in the SS Folder.

Generate and Save the VecTor2 Structure File in the SS Folder.

Generate and Save the VecTor2 .job File in the SS Folder (can

change modelling Assumptions).

Check the Number of Analysis Steps.

Change Modelling Format to 3.

Create/Copy the NICON.txt file to the SS Folder.
