Hello,
I was doing a eigenvalue buckling analysis to find the first buckling mode. The static structural part works well, but it fails to solve the eigenvalue buckling part.
The solver output demonstrates following warning messages:
SUBSPACE CALCULATION OF UP TO 1 EIGENVECTORS.
NUMBER OF EQUATIONS = 76830
MAXIMUM WAVEFRONT = 54
MAXIMUM MODES STORED = 1
MINIMUM EIGENVALUE = -0.10000E+31
MAXIMUM EIGENVALUE = 0.10000E+31
CENTER EIGENVALUE = 0.00000E+00
Local memory allocated for solver = 61.549 MB

Total memory required for out-of-core solution = 96.285 MB
*** NOTE *** CP = 7.109 TIME= 13:23:45
The Distributed Sparse Matrix Solver is currently running in the
in-core memory mode. This memory mode uses the most amount of memory
in order to avoid using the hard drive as much as possible, which most
often results in the fastest solution time. This mode is recommended
if enough physical memory is present to accommodate all of the solver
data.
*** WARNING *** CP = 11.016 TIME= 13:23:49
There are no solutions in the selected range.
*** NOTE *** CP = 11.016 TIME= 13:23:49
There are no modes in the specified range.
*** NOTE *** CP = 11.016 TIME= 13:23:49

How could this problem be solved?
Thanks.
