It looks like you have about 10 peaks each 100 iterations, thus 10 iterations per timestep. I guess you did not switch off the convergence critertion. Go to monitors ->...

Hey, i) Is this 2d? ii) Did you try any other turbulence model / stationary case and got better convergence? iii) Did you try to improve the grid? It looks like you have several "jumps" in your...
