If you haven't looked at the new family of contact elements with 5.5, you
should give them consideration. I just finished two very similar pin
interference with axial force problems. They are 3D and used Target 170's
and Contact 174's. Some aspects are tricky to use; however, not nearly so
tricky as with 48's and 49's. For 2D analysis, use Target 169 and Contact
171 & 172. All solved very nicely with the PCG solver, solution control, &
line search.

Hello all,
My problem is this:
I have a part (A) that is press-fit into another part (B). There is a
pressure loading on part A that pushes it up against a shoulder on part
B. I have established contact with contac48 elements for the press fit
and the contact where the shoulder on B stops part A from moving.
The model is setup so that part A is located in part B with
interference. Part A is not touching the shoulder of part B it is about
0.0005 meters form contacting the shoulder. When the model is run I
would like Part A to slide against the shoulder on part B so that I can
see the Stress at the contact location. I have tested the model by
changing constraints and have verified that the press-fit contact is
working. The problem is that the contact between part A and the
shoulder is not working. I get an error saying something to the tone of
there is too much displacement, or to few of DOF's
Is there a different type of contact element that needs to be used for
this situation?
Any help is appreciated.
