Dear all,

I am working on modeling of human knee articular cartilage.
I have made the model, but i don't understand why the solution is getting terminated ?
I can see only one error

***ERROR: TIME INCREMENT REQUIRED IS LESS THAN THE MINIMUM SPECIFIED

I am pretty sure that someone of you know about what happening inside and why solution is getting diverging.I think, contact conditions and boundary conditions are ok...

HERE I AM ATTACHING MY INPUT FILE,

Please help me to solve this problem...........

Thanking you in advance !

Regards,
