A uniform mesh would be the same element size throughout. You do not want a uniform mesh for a CFD model. You want small elements at the surface, and growing in size gradually from the surface as well as throughout the mesh (between blocks). Use the “Edge Params” to set spacings and ratios to get gradual growth from the surface as well as between blocks. Your last picture looks appropriate for a CFD mesh. Different element sizes in the mesh anywhere will necessitate denser mesh regions than other regions. You must only ensure that mesh sizes grow gradually between these regions, not abruptly. It sounds like you need some learning on what should be done in the mesh for a CFD analysis. I’m sorry but I can’t keep responding to this post anymore if you essentially keep asking what are in content the same questions over again.
