Modal FRF - Define Loads
After selecting the modes from the Define Modes tab, select nodes at which unit excitations or actual excitations can be applied.
- Nodes
- Select nodes and activate DOFs for applying excitations.
- Unit Input
- Generates sensitivity subcases with unit excitations at selected nodes. The number of subcases is equal to the number of selected nodes multiplied by the DOFs.
- General
- Defines external excitations using the CSV, solver deck, and test UNV file. This generates a general FRF subcase with defined excitations.
- Table name
- Enter the name for the external excitations defined.
