NOTE

In the case of solid elements, the Eigen analysis results shows very good agreement with the Nastran results. But, in the case of shell elements, the Eigen analysis results can be little different from the Nastran results.

If the shell type element (CTRIA3 or CQUAD4) is used and some result related the normal rotation stiffness is different. Please check and set a specific value to Shell Drilling Stiffness on option dialog of RFlexGen.
