I'm trying to model an interference condition for a compound pressure vessel with axisymmetric 2D behaviour.

However, even after modelling geometrical interference (~ 0.1 mm) as shown in the below image, the initial contact tool status shows "Far Open" but there should have been some finite penetration. Further due to this, there is no interference stress developed after solving the model.

Can someone help me to understand why I'm facing this issue?
