Physics preference in ANSYS Meshing are :Mechanical, Electromagnetics, CFD and Explicit.
Meshing methods available for 3D bodies :Automatic, Tetrahedrons, MultiZone, Hex Dominant, Sweep, CutCell.

Meshing methods available for 2D bodies : Automatic Method (Quad Dominant), Triangles, Uniform Quad/Tri,
Uniform Quad.
1.Automatic Meshing Method, If you select the automatic method control, the body will be swept if possible.
Otherwise, Tetrahedrons (Patch Conforming) is used.

The global Element Midside Nodesoption allows you to control whether meshes are to be created with midside
nodes (quadratic elements/second order) or without midside nodes (linear elements/first order). Reducing the
number of midside nodes reduces the number of degrees of freedom. Choices for the global Element Midside
Nodes option include Program Controlled, Dropped, and Kept.

Program Controlledis the default. For surface bodies and beam models, Program Controlledis identical to the
Droppedoption described below. For solid bodies and 2-D models,Program Controlledis identical to the Kept
option described below.
The Droppedoption removes midside nodes on all elements. Examples shown below are for a solid body.
The Keptoption retains midside nodes on elements created in the part or body. All elements will have midside
nodes.

2. Tetrahedrod/Hybrid Meshing Method, where an all tetrahedral mesh is created. An algorithm setting is
displayed allowing you to choose how the tetrahedral mesh is created based on your choice of one of the
following options :
a) Patch Conforming Algorithmfor Tetrahedrons Methods Control :
Bottom up approach : Meshing process starts from edge, face and then body
All faces and their boundaries are respected and meshed
Good for clean CAD geometries

7/14
b) Patch Independent Algorithmfor Tetrahedrons Method Control :
Top down approach : The volume mesh is generated first, and this is projected on to faces and edges to
create the surface mesh
The faces and their boundaries (edges and vertices) are not necessarily respected if they fall under a
specified tolerance, unless there is a named selection, load, boundary condition or other object scoped to
them
Good for gross de-featuring of dirty CAD geometries
Patch Conforming Method. Faces, edges and proximities are respected and resolved.

Patch Independent Method. Defined name selections before grid generation process.
3. Hex Dominant Meshing Method, where a free hex dominant mesh is created. This option is recommended
for bodies that cannot be swept.

The mesh contains a combination of tet and pyramid cells with majority of cell being of hex type. Hex dominant
meshing reduced element count.
4. Sweep Meshing Method, a sweep mesh is forced on sweepable bodies (including axis-sweepable bodies,
which are not displayed when you use the show sweepable bodies feature). The mesher will fail if a swept mesh
cannot be generated on a body with a sweep method control.

ANSYS Meshing can find sweepable bodies in the geometry automatically.
5. MultiZone Meshing Method, based on blocking approach used in ANSYS ICEM CFD Hexa. It automatically
generates a pure haxehedral mesh where possible and then fills the more difficult to capture regions with
unstructured mesh. The MultiZone mesh method and the Sweep mesh method operate similarly; however,
MultiZone has capabilities that make it more suitable for a class of problems for which the Sweep method would
not work without extensive geometry decomposition.
