Two connected flat plates (0.05m * 0.01m * 0.002m, 0.025m offset) with one end fixed and an vertical force of 100N at the other end. Plates connected with a bonded contact. Reference model has been partitioned to have two exactly overlapping faces at the connection. The second model uses the position tolerance feature of the Code_Aster solver to connect only nodes near the master surface.
A moderate second order automatic tetrahedral mesh was created for both geometries, resulting in a mesh size of 376K nodes for the partitioned model and 379K nodes for the unpartitioned one. The solution takes about 25min with a 4-Core machine and an iterative linear system solver solver (GCPC).
Comparison of deflection in vertical direction:
- Reference Solution (partitioned model): 8.0076 mm
- No Tolerance: 0.36005 mm, relative error: -95.5%
- 0.1mm Position Tolerance: 8.0058mm, relative error: -0.02%
