Reaction force on bolt (SPRINGA element)

General Questions

PrePoMax crashes for me when I try to make custom keywords active, but I see that you are trying to define a quadratic (3-node) beam element using only 2 nodes:

*ELEMENT, TYPE=B32, ELSET=beam_1
9000001, 42733, 42735

*ELEMENT, TYPE=B32, ELSET=beam_2
9000002, 42737, 42739

You need to add nodes in the middle with *NODE. See the syntax here: Simplified bolt connection with beam element and rigid constraints - #3 by qfontaine
