I'm trying to calculate a nomal Bolt Pre Load with 1D Elements.
After calculation, there's a displacement which is not possible.
Now someone told me, that i can fix this Problem with the REDFAC = 1 Parameter in the Nastran File.
But i don't know exactly where i can write i down.
Thank your for your help
If you want this to apply to all pairs, the format would be:
BCTPARM, 100, REDFAC, 1.0
If you wanted it to apply to an individual contact pair, the format would be:
BCTPARM, 101, REDFAC, 1.0
Note that BCTPARM is a bulk data card. It can be anywhere in bulk data. I'd suggest putting it near the BCTADD/BCTSET cards.
