Hi,
I am trying to do buckling analysis with 100 N compression load and 1800 mm length model.
The model has Foam and HLP material and both material components contacted with Freeze contact.
but results are not good, showing Lanczos solver warnnings.
Lanczos solver warnnings for eigenvalue subcase 2.
- At some point in the process, an inconsistent inertial count was found.
This implies that some of the calculated frequencies may be inaccurate,
especially the duplicated frequencies. To avoid this, specify both bounds
and keep the bound away from the currently calculated frequencies.
*** warning *** the rayleigh quotient
