SubscriberHi,
I'm curious about why extract stiffness and mass matrix.
What can be known by extracting the matrix?
Thanks in advance

Ansys EmployeeHi,
In structural analysis, stiffness and mass matrices are utilized to address both static and dynamic issues. For example, they are employed in design analysis to compare or validate outcomes. For instance, the matrix iteration approach can be used to determine an airplane’s highest natural vibration frequency using the mass and stiffness matrices.
In design analysis, you may want to extract the full or sparse stiffness and mass matrix generated in a modal analysis or stiffness matrix generated for steady-state analysis to verify or utilize it for comparison purposes.Please review the following posts, as they will provide assistance in the extraction of matrices.
Thanks,
Deepak
