Eigenvalue solver settings

Use the Solver Settings command to modify eigenvalue solver options. The eigenvalue solver computes the current mode shapes and frequencies taking into account design variable sensitivities. This computation is done on the reduced model considering only DOFs that are in the A-Set DOF or U-Set DOF.

Where do I find it?

Application	Pre/Post
Prerequisite	An active Model Update solution process
Simulation Navigator	Right-click the Model Update node → Solver Settings
Command Finder	Solver Settings
Menu	Tools → Model Update → Options → Solver Settings
