Mesh

Some of the settings you can use to get a better mesh is shown in the figure below.

  • The Relevance Center can be set to coarse, medium and fine. After you pick the Relevance Center, you can change the Relevance from -100 to 100, with 100 being the finest within the particular relevance center.

You can insert a sizing for faces and edges along with the mesh settings in the figure.

You can give a bias to edge sizing to cluster cells towards one end of edge. See this page for how to implement a bias to an edge.



Below is a mesh we obtained by playing with these settings. This mesh resolves the separated flow behind the plaque better than the default mesh. It can be further improved though!
