Hi everyone,
I'm trying to simulate a large displacement of a component along a direction and with contact with an other component. The first one should deformed the second one. Abaqus works for a displacement inferior to 15mm but after calculus do not converge, increment became too small.

Part : 3D both
Tangential behaviour : Friction less
Normal behaviour : Hard contact
Tube is the surface master
Someone get an idea ?
Thanks !
Error abaqus :
*********This is usual (<15mm) and it works with that*************
18 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.
There are 2 unconnected regions in the model.
*********This is not usual (>15mm) ************************
There is zero FORCE everywhere in the model based on the default criterion. please check the value of the average FORCE during the current iteration to verify that the FORCE is small enough to be treated as zero. if not, please use the solution controls to reset the criterion for zero FORCE.
Displacement increment for contact is too big.
