Hi, everyone.

I am a student and I am working on my thesis with the CFD on the train model.

I am having a problem with convergence on my model and I could not locate the problem causing this. Please see attached picture of the plot.

The cell count was 4.5 million, wind tunnel model.

Any advice will be very helpful. thank you.
