The MultiZone mesh method provides automatic decomposition of geometry into mapped (structured/sweepable) regions and free (unstructured) regions. It automatically generates a pure hexahedral 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.
In this tutorial, you will learn tocreate a structured mesh (hexahedral mesh) using Ansys Meshing. In this case, the geometry is a hollow cylinder.
Ansys Meshing – Body of Influence
The Body of Influence option is available in the Type field if you selected a body and Use Adaptive Sizing is set to No. Using this option, you can set one body as a source of another body
Ansys Meshing – Sphere of Influence
The Sphere of Influence option is available in the Type field after you select an entity such as a body, face, edge, or vertex.

Ansys Meshing – Mesh Copy Control
The Mesh Copy control enables you copy mesh from one body to another. This option can be used to reduce the mesh setup time for repetitive bodies/parts. Association to CAD is maintained after performing mesh copy.
Mesh controls are scoped only to the source anchor body. When the mesh is generated, the source anchor body is meshed and the mesh is then copied to targets.
Ansys Meshing – Pinch
The Pinch feature lets you remove small features (such as short edges and narrow regions) at the mesh level in order to generate better quality elements around those features.
Ansys Meshing – Mesh Types (Hexa, Prism, Polyhedral)
When geometries are complex or the range of length scales of the flow is large, a triangular/tetrahedral mesh can be created with far fewer cells than the equivalent mesh consisting of quadrilateral/hexahedral elements.
Ansys Meshing – Element Order (Linear & Quadratic)
The global Element Order option allows you to control whether meshes are to be created with midside nodes (quadratic elements) or without midside nodes (linear elements).
Ansys Meshing – CutCell
The CutCell meshing process involves the following approach:
Objects, material points (optional), and size functions are defined.
The initial size of the Cartesian grid is computed based on the minimum and maximum size set for the size functions.
