I was reading several papers related to wind flows around building structures and I found that they presented their meshing techniques (refinement and type) on the surfaces of those building models and grounds as shown in the following figures (coursey of Blocken et al. 2007 and Van Hoof and Blocken 2010 respectively). I'm using Design Modeler, the standard Ansys Mesher, and Fluent. So I would like to know how to visualize the mesh in the manner shown below?
Thank you for your support.
