Save Bolt Load Results

I'm running a model in which I have a bolt preload and several load cases, which I'd like to run one case at a time. Is it possible to run the bolt preload only, save those results, and reuse them on subsequent Nastran runs?

Re: Save Bolt Load Results

Nastran does not allow restarts with boltloads or contact. See the following in the QRG under the BOLTLD case control command:

 

REMARKS:
1. Bolt preload is supported in SOLs 101, 103, 105, 107 through 112, 401, and 601.
2. Bolt preload is not supported in a solution RESTART.
3. The following remarks appy to SOLs 101, 103, 105, 107 through 112.
• Subcases with BOLTLD case control commands should be either the first or
the last.
• In SOLs 101, 103, 105, 107 through 112, for the special case where the
sparse solver is used, the model does not contain contact, and the keyword
scratch = yes, BOLTLD case control commands in the subcases must be
