Hi,

Check that your mesh is of sufficient quality and properly resolves the boundary layer near the submarine’s surface. Use a mesh refinement study to verify that the drag coefficient is not significantly affected by mesh size or grid resolution.Check the y+ value after the computation again as the real flow field will develop during the simulation and a remesh might be necessary.

Thank you.
