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 modes.
Solver. Sets the solver to be used in performing buckling analysis.
Automatic. The software selects the solver based on the study type, analysis options, contact conditions, etc.
Direct sparse. Uses the Mode Extraction Routine powered by the Direct Sparse solver to perform buckling analysis.
Use soft spring to stabilize model. Adds soft springs to stabilize inadequately supported models. See Static analysis properties for more information.
FFEPlus. Uses the FFEPlus iterative solver to perform buckling analysis.
Results folder. Sets the location of the results of this study. By default, this location is set by the Results folder options.
