Bolt preload analysis using Optistruct

Altair Forum User

Hello everybody,

Could you please tell me how to do bolt preload analysis in Optistruct.

I mean not using any other solver e.g. Radioss , Nastran.

Thanks in advance,

Hi Omkar,

You can use CGAP element with the U0 or F0 field (PGAP card).

If you use the new contact interface (optistruct 10.0), you can use GPAD field on the PCONT.
