Nastran SOL106

Nastran SOL106

hi. i have to perform a nonlinear normal mode analysis using nastran. however, the results obtained with the SOL103 are the same as those obtained with SOL106 with very large displacement. i dont seem to know what the problem is. can someone please help. thank you!

RE: Nastran SOL106

Its hard to guess. If you can send your model or generate a test model which captures what you have described that could help identify the issue.

RE: Nastran SOL106

SOL103 is a normal mode solver. Obtained displacements have no physical science.

RE: Nastran SOL106

thank you both. i finally figured out why the normal mode analysis results were the same in sol 103 and sol 106. the latter require pre loading for the nonlinearity to be activated.
