Hello,

I am having this outlet domain. Where the black arrows indicate the walls while the red the inlet and the outlet.
I am trying to create a mesh and it is important to catch the boundary layer, however using a structured mesh isn't the solution since in the inlet the lines for the boundary layer will be to many while in the exit the lines will be fewer since the geometry is diverging.
So I came with this idea of creating an unstructured mesh. Is this possible with ansys meshing? If yes how?



Do you propose anything else? I am a very new user to cfd and I am just making assumptions
