I have question on fea.
Trying to run fea simulation which includes bolted connection.
I am not sure which contact constrain to use between bolted faces and between bolts/bolting faces.
Attached is showing result of fea.
Part is jacking frame which is used to lift cylindical object.
Tow supports (shown as half bar) are simulating jacking cyliners and
bottom facces are fixed constrain and contact is sliding no separation.
