ANSYS Meshing Application Introduction-Surface Meshing

•Meshes for 2D Analyses

•Meshing Methods for Shells and Surface Bodies

– Automatic Method (Quadrilateral Dominant)

– All Triangles

– Uniform Quad/Tri

– Uniform Quad

•Surface Meshing Mesh Controls

•Surface Meshing and Inflation

•Workshop 9.1   Meshing a Surface Body for a 2D Fluent Analysis

•Both Fluent and the Mechanical Products in the ANSYS
Portfolio accept 2D (Surface) Meshes for 2D Analyses

•Surface meshes or shell meshes are created for Surface Bodies
created in DesignModeler or other CAD package

•CFX does not accept Surface Meshes as it is inherently a 3D Code. 
To do a 2D analysis in CFX, create a volume mesh (using Sweep)
that is 1 element thick in the symmmetry direction for a

– Thin Block for Planar 2D

– Thin Wedge (< 5°) for Axisymmetric 2D

•The Surface Meshing methods discussed in this lecture are therefore appropriate for Fluent CFD or ANSYS Mechanical simulations

•Meshing Methods for Surface Bodies

– Automatic Method
(Quad Dominant)

– All Triangles

– Uniform Quad/Tri
