The time step size did change much for the last 50 time steps. Between 1.3755e-3 - 1.44e-3. The max time step is 35 and the simulation consistently converges around 10th - 8th time step. 

 

I did not save the data file because I have a different model that runs without issues, except it has significant reverse flow that leads to mass loss at the inlet. I made some changes to the shape of the inlet to try to eliminate of reduce reverse flow.
