Does anyone have knowledge of the MSC for Windows version 2004 settings that will produce modal results matching earlier NASTRAN results, such as from version 70. I have accounted for what I know as the new default settings (snorm, k6rot) and forced others to be equivalent, but I have as yet been unable to get matching modal results for the same (even painfully simple) model. This is a significant problem in a field where models are baselined and results “canonized” as the standard for community reference.
