Hello dear,
i am trying to perform a buckling analysis to rod,
but before buckling,
in the first step i need to perform interference fit,
in the second step, i need to perform bolt pretension
in the last step i need to do nonlinear Buckling,
i did some operations but i am new for optistruct,
after interference fit in the second step i come across with faulties so that the calculations stops
can you please check the model?
i updated the latest model that i use for calculation
in the previous model,
i had problems to start the second step after first step,
i was performing interference fit but i had problem in the begging of bolt pretension so that i did changed the master - slave for bolting,
then i got the latest version which i attached.
in the attached model, i was able to start bolt pretension after interference fit but i came across with a problem, so that i am not sure if i have some problems in the defitions because i am new for using optistruct.
i use Hypermesh 14.0.2 version
thanks you so much
