PARAM, AMSFRMAT

Bulk Data Entry This parameter controls the method used for modal frequency response solution when frequency-dependent materials are present and AMSES is used as the eigensolver.

Parameter Values Description
AMSFRMAT <YES, NO>

Default = NO

YES
An alternate method is activated for modal frequency response solutions when a large number of frequency-dependent materials (> 1000 dof) are present and AMSES is used as the eigensolver. This alternate method can help improve the performance of the modal frequency response solution.
NO
The alternate method is not activated.
