Tested with CGX 2.19/ CCX 2.19
- Assembly with
*tieor*contact pairconnections. Contact version is selected via parametercontactinpre.fbd.par. - Thermal strain with prescribed temperature
- Symmetry expansion in post-processing

bf |
100 | flange width in mm |
length |
500 | length in mm |
tw |
10 | web thickness in mm |
hw |
100 | web height in mm |
a |
7 | seam thickness in mm |
dls |
25 | seam offset in mm |
contact |
"pc-ss" | contact version: "pc-ss" (penalty, surface to surface) or "tie" (MPC contact) |
Create the file pre.fbd and run the pre-processing

Penalty contact is less rigid than MPC contact, thus the maximum equivalent stress for MPC contact is higher.
Vertical displacement
