  • Knowledge Base

Product Feature

In the Modal Analysis add-on, you have the option to automatically increase the sought eigenvalues until reaching a defined effective modal mass factor. All translational directions activated as masses for the modal analysis are taken into account.

Thus, it is possible to easily calculate the required 90% of the effective modal mass for the response spectrum method.
