Obtain results with NASTRAN
Obtain results with NASTRAN
(OP)
Hi. I have in NASTRAN a case with one load set and two constraint sets. I want to run next cases:
-Load set 1 with Constraint set 1
-Load set 1 with Constraint set 2
But I'd like to obtain these results at the same time, I mean for just one analysis.
How can I do it?
Thank you very much.

To run one or more Bc's, in Nastran, use spcadd card for n number of the Bc's and specify loadsteps for each subcases. i.e., for each and every Bc's specify subcases.
I think if you try to do the above mentioned point, u will get the result.

RE: Obtain results with NASTRAN
I believe that the SPCADD will only combine the SPC sets in Nastran. In jwirtz's example, it would be equivalent to running Load Case 1 with Constraint Sets 1 and 2 simultaneously. If that is what is desired, then the SPCADD would be the proper way to combine the constraints. If you want to run an analysis using Load Case 1 with independent Constraint Sets 1 and 2, I believe you will need to run two separate subcases and combine the results later (if the combination is meaningful).
