Hello all,

I want to study the behaviour of airflow around a 2d airfoil in a specific angle of attack. More specifically, my investigation concerns the performance of different RANS models, validating my results with those in the literature. A given grid has been provided for this purpose.

The problem is that in my task, I should use the 'rotate geometry' option to modify the given grid and check the airflow in my angle of attack. I didn't find anything about this option. Is it possible without changing the properties of the grid provided? Could anyone tell me how I can do it? I tried to rotate the whole mesh in the existing Cartesian system of coordinates but I don't like the way that it works. What if I just change the velocity components?

Thanks in advance for your help

Typically it is done by changing the velocity components.
But if you want to simulate the flow over an oscillating airfoil then you will have to change the grid.

Thank you.
