ANSYS does not output any eigenvalue for the model

      This happens when ANSYS is not able to find solution to the eigenvalue problem. User may try to insert a Command Snippet object with command BUCOPT under Analysis. It is recommended to input a nonzero SHIFT value and a reasonable LDMULTE value (i.e., a smaller LDMULTE that is closer to the last buckling mode of interest) when numerical problems are encountered.
