PARAM, DISIFMCK
Bulk Data Entry Skip indefinite mass matrix check.
| Parameter | Values | Description |
|---|---|---|
| DISIFMCK | <YES, NO> | For
vibrational eigenvalue analysis, the mass matrix must be positive
semi-definite. However, if this is simply caused by numerical
ill-conditioning, then
PARAM,DISIFMCK may be used
to skip the indefinite mass matrix check.
