Convergence not Reaching!

Sure @jousefm iw ill share the paper, dont have a soft copy of it yet.
As for results for the stationary case i am getting values of coefficients of drag and lift as 0.996 and 0.684. Whereas in the paper they are getting as 0.868 and 0.618. So i am getting a 14.6% and 10% error but the reasons for that could be because they have use RNG K Epsilon model and we are using Transition KW SST and they’ve conducted on ansys fluent whereas i am using simscale. So that in future to all my juniors i can suggest using simscale. That’s one of the reason that i keep asking so many doubts because i want my doubts t be crystal clear so that i can clear doubts of others. In a way i am trying to promote simscale you can say :wink:

Now coming back to the boundary conditions you mentioned. I tried for the rotating case of the tyre applying the same conditions as you suggest but the error is coming alot approx 35 % and also as i mentioned i saw in one of the Formula SAE workshop session that to capture the flow around the rotating spokes/rims they create a MRF region just around the spok. So when i am trying to do that and give meshing ( This brings me back to the other POST ) Mesh error is coming. All the conditions i have kept same but still its coming. Soo please can you help me out with it. Another constraint is that i cannot change the base mesh box size rest all stuff can be altered, well at the end i want my result. so please can you help me out with the meshing.

Also can you please answer this :-
Is it converged ? But the tolerance is given as 0.000001 and shouldnt all the convergence lines go below that for convergence to reach ? I saw it in some of the sample projects so thatswhy asking.
