Contact and convergence error

Good morning,

 

I'm running a transient analysis of 2 gears (one of them with a preload and the other one with an imposed rotation). When I run it with Optistruct I get 2 problems:

  •  *** ERROR # 4965 ***
     Maximum number of time increment cutbacks reached,
     analysis aborted.
  • The biggest problem comes here, if I analysis the results, the contact status is 0 everytime. The gears rotate but they don't seem to have a good contact. Moreover, I get high normal contact forces at points where there should be any contact (see image attached).

 

I also attach the .fem to make it quicker and the .out from the previous simulation

 

Thanks!!
