Use the Buckling
dialog box to set the desired options for the active buckling study. You
can also include flow and thermal effects
in the study.
Number of buckling
modes. Sets the number of buckling modes to be calculated. The
program calculates the buckling load factors and the associated buckling
for no penetration contacting surfaces (slower).
This method produces continuous and more accurate stresses in regions
with definitions of no penetration contact. The method is used when defining
contact between faces to faces and faces to edges. When this option is
selected, the software may take more time to solve the problem. This method
is referred to as mortar contact in the literature.
contact. When this option is checked, the program overrides the
default surface-based bonding contact and resumes to node-based bonding
contact. Check this option only in cases you run into performance issues
when solving models with extensive contact surfaces. The default option
of surface-based contact formulation results in longer solution time than
the node-based contact formulation.
Bonding is most accurate when
the mesh is compatible.
Sets the solver to be used in performing buckling analysis.
The software selects the solver based on the study type, analysis options,
contact conditions, etc.
Uses the Mode Extraction Routine powered by the Direct Sparse solver to
perform buckling analysis.
Uses the FFEPlus iterative solver to perform buckling analysis.
