The Normal Mode Extraction panel can be used to create load collectors for each
of the subcases in the model. The panel is shown in the figure below. Figure 1.
The Normal Mode Extraction panel allows you to perform the following operations
Select Subcase
Select the required method
EIGRA - Defines the data required to perform real eigenvalue
analysis with the Automated Multi-Level Sub-structuring
technique.
EIGRL - Defines data required to perform real eigenvalue analysis
(vibration or buckling) with the Lanczos Method.
Define the values for
Minimum frequency
Maximum frequency, or
Number of Modes
Note: Value fields contain default values. You can
use the same or you can modify according to the
needs.
