Hi!

Is it possible to run a NLGEOM analysis with bolt pretension. I find that pretension is not suppoerted in geometric non-linear analysis. Is it really so? Is there some workaround solution?

I'm using HW version 12. I see that version 13 has a new analysis type: large deformation non-linear analysis. Would that support bolt pretension subcase before loading?

Best regards,

Andras

    Hi, can you explain where the pretension loadstep is linked to the NLGEOM loadstep card?
