Subcase Repeater
Description: Allows alternate eigenvalue results output selection.

Number of modes to be output for the specified subcase.

Integer > 0

Remarks:
- This command is best described with an example. It is desired to output element forces for the first four modes only, then element strain energy for the next two, and element stress for all remaining modes. The following example demonstrates this:
| SUBCASE 1 $ FOR MODES 1 THRU 4
|
|
|
MODES = 4
|
|
|
FORCE = ALL
|
| SUBCASE 5 $ FOR MODES 5 AND 6
|
|
|
MODES = 2
|
|
|
ESE = ALL
|
| SUBCASE 7 $ FOR MODES 7 AND REMAINING MODES
|
|
|
STRESS = ALL
|
- If this command is excluded, all eigenvalue results are considered to be part of a single subcase.
- This command can also be used to suppress output after a certain number of modes have been output. For example, to suppress all eigenvalue output for modes beyond the first five, the following Case Control could be used:
| SUBCASE 1
|
|
|
MODES = 5
|
|
|
STRESS = ALL
|
| SUBCASE 6
|
|
|
DISPLACEMENTS = NONE
