CFX! Su urface M eshing af is traditionally slower than delaunay af produces higher quality elements at boundaries af mesher cannot mesh closed surfaces af is less robust on surface meshes with large variation in edge length scale around a surface mesh vertex surfaces with small gaps Delaunay mesh quality is not good on poorly parameterized surfaces Delaunay works on closed surfaces CFX5.5V5.5.1H 2001AEA Technology
