Is there a way to save modal quantities for future calculations?

david_ur_1

The process of EIGRA or EIGRL is often time consuming and coming back to a model to recalculate a different forced response requires recalculating the whole modal space again.

Any input on the topic will do,

Thank you!

Hi David,

You can use EIGSAVE to save eigenvalues and eigenvectors, then use EIGRETRIEVE to retrieve them on a Modal frequency response or Modal transient response.

EIGVSAVE

EIGVRETRIEVE
