I tried to use Lanczos algorithm in abaqus by using:
*frequency, EIGENSOLVER=LANCZOS
However an error message appeared saying:
Sparse solver must be used.
Actually, I specified Sparse solver in the keyword:
*heading, sparse.
The algorithm is only available for abaqus v5.8 and I have only access to
the manual for v5.7. I guess that I must specify the sparse solver when
specifying the use of Lanczos algorithm.
Could any one over there please give me further information about the usage
of the Lanczos algorith in abaqus v5.8.
Thanks.
