3 Detailed output on cost and convergence
Remarks:
1. Buckling is not supported.
2. KGG and MGG must be real and symmetric
3. INVEC may be purged.
LANCZOS
Performs real eigenvalue analysis
4 More detailed output on orthogonalizations and some extra
arithmetic to check on orthogonality
MAXSET Input-integer-default=7. Vector block size for Lanczos method only.
The actual value of block size may be reduced depending on available
memory and problem size.
SHFSCL Input-real-default=0.0. Estimate of the first flexible natural frequency.
SHFSCL must be greater than 0.0.
NORM Input-character-default=' '. Method for normalizing eigenvectors. By
default (or NORM='MASS'), MASS normalization is performed.
NORM='MAX' selects normalization by maximum displacement.
EPSNO Input-integer-default=-1. Number of eigensolutions to check and the
quantity of error checking output. If left at its default value, only the
highest epsilon for the first ten or NEIGV modes (whichever is less) are
printed. If EPSNO is greater than zero, the epsilons for the first EPSNO
are printed.
NOQG Input-integer-default=1. Single point forces of constraint matrix
creation flag. Default of 1 requests computation of the forces. Specify -1
to request no computation.
NOQMG Input-integer-default=1. Multipoint forces of constraint matrix creation
flag. Default of 1 requests computation of the forces. Specify -1 to
request no computation.
4. QG and QMG are created only if USET is specified and NOQG and NOQMG are
specified to 1.
