I have meshed and ran a simulation of a jet into a quiescent fluid. The simulation diverged, and I've gone back to try and improve the mesh. I have some skewed elements close to the inlet patch that have been identified using ICEM check mesh.

Attached is a picture of the circular inlet, and the front wall patch. They are both located at x = 0. I would like to add circular rings/inflation layers around the inlet outer edge because that is where skewed elements were identified. I am hoping that improving the surface mesh will lead to better volume meshing close to the inlet, especially in the shear layers.

Any help greatly appreciated.

P.S. I am meshing with unstructured elements because this is a simple test case that'll become more complex and require unstructured meshing.
