LANCZOS
Performs real eigenvalue analysis
QG Single-point constraint forces of constraint matrix in the g-set.
QMG Multipoint constraint forces of constraint matrix in the g-set.
Parameters:
FORMAT Input-character-no default. Problem type. Must specify 'MODES'.
Buckling problems are not supported.
NEIGV Output-integer-no default. The number of eigenvectors found. Set to -1
if none were found.
NSKIP Input-integer-default=1. Subcase record number to read in CASECC for
the METHOD set identification number.
FLUID Input-logical-default=FALSE. METHOD command option (FLUID or
STRUCTURE). If FLUID=TRUE, the EIGRL entry is selected from
METHOD(FLUID) Case Control command.
EPSORTH Input-real-default=1.0E-10. Unused.
SID Input-integer-default=0. Alternate set identification number.
If SID=0, the set identification number is obtained from the METHOD
command in CASECC and used to select the EIGR, EIGB, or EIGRL
entries in DYNAMICS.
If SID>0, then METHOD command is ignored and the EIGR, EIGB, or
EIGRL is selected by this parameter value. All subsequent parameter
values (METH, F1, etc.) are ignored.
If SID
