Hello Everyone,

I am trying to do a steady simulation of S805 Airfoil. Whenever I try to generate a prism layer around an airfoil I am getting a prism layer as shown in the image below. I tried to play with a lot of expert properties (i.e Near core aspect ratio, concave angle, convex angle, layer reduction ratio etc.) but no success!
when I reduce the total prism layer thickness below a certain value I am getting a smooth prism layer but when I increase it I am getting a prism layer as shown in the image

Hello,

I am assuming that you are using the Prism Layer Mesher? I used to have the same problems as you.
Try out the Advancing Layer Mesher instead. It maintains a consistent prism layer height.

Hope it works.

Hello D. Lehnardt,

I am using Automated Mesh (2D) for meshing after Badging for create 2D mesh. I don't see an option of Advancing Layer Mesher in Automated Mesh (2D).

So I tried using the Automated Mesh with Advancing Layer Mesher after Badging but the problem is I don't see any prism layer's (I can see prism layer's at planes other than z=0).Also I doing volumetric refinement using various volume sources but I cannot see any refinement either though it takes a lot of time to mesh which implies that it is meshing but I can't see it. I am using Polyhedral Mesh with Advancing Layer Mesher.

Your help will be much appreciated.

Best,
Shadab
