I am trying to simulate a gear assembly to analyse stress distribution around the gear teeth. It is a non-linear static with contact interaction analysis. I have used Hexmesh for the geometry. After 50% of the simulation, i am getting the error:
*** ERROR # 4965 ***
Maximum number of time increment cutbacks reached,
analysis aborted.
Could anyone please help me with this issues.
I have attached the output file and a presentation for your reference.
