Hello, I have encountered this error when running my simulation.

*** ERROR # 4966 ***
Minimum time increment reached,
analysis aborted.

I do not know how to solve this problem. I have attached the .hm file. Appreciate any help thank you.

Hi Mohd,
Please try using contact pair with friction instead of stick.
Also use MPA units to see if your model runs. Don't forget to scale it to use mm, if necessary, and correct the loads, mass, etc. Anyways, double check all units and material data.
Another option is to use CONV: UP in NLPARM.
Finally, use a higher initial increment (NINC) in NLPARM, increase the minimum increment (DTMIN) in NLADAPT, also increasing the number of cutbacks.
Please let me know if works for you.
