how to create pin joint in 3D meshing
Altair Employeei am solving a problem with 3D mesh..i have a lug and pin joints in it. I want to model it using a 1D element..how can i do that?

thanks for your response sir,
i am unable to open the file which you have sent me. Can u kindly explain how to do it? i will try on my own

Hi,
sorry for the file is corrupt
when you want to make pin join, rotation around axle of beam must be released, this dof is 4
so create your beams with pin a = 4
connect beam with hole by 1 rigid only, so you'll not encounter dependency error (check F10>1d>dependency before run analysis)

thanks for your response..
i have modeled it as follows.
> i created one rigid on either side.
> connected independent nodes 1D beam with pin a =4 and pin b= 0
is that a right way to do it?

and on the top lugs.. i wanted to constrain them..i.e only rot y is allowed and all other dofs are constrained..i ve created a pin joint there..later i have given constraints as in model..is it a right way to do it?

You can connect like in this
and create constraints at master node of RBE2, beams are not necessary there
I modify your file here (import solver deck this optistruct *.fem file)

thank you very much sir
