For solid models, meshing technologies from ANSYS provide robust, well-shaped quadratic tetrahedral meshing on even the most complicated geometries. With automatic contact detection and setup, a user requires little training to perform sophisticated analysis. In addition, users can generate pure hex meshes using one of several mesh methods, depending on the type of model and whether the user wants a pure hex or hex dominant mesh.

ANSYS meshing technologies provide physics preferences that help to automate the meshing process. For an initial design, a mesh can often be generated in batch with an initial solution run to locate regions of interest. Further refinement can then be made to the mesh to improve the accuracy of the solution. There are physics preferences for structural, fluid, explicit and electromagnetic simulations. By setting physics preferences, the software adapts to more logical defaults in the meshing process for better solution accuracy.

Other physics-based features that help with structural and explicit dynamics include:
• Automated contact handling
• Automated beam and shell meshing
• Editable contact definitions
• CAD instance modeling/meshing
• Rigid-body contact meshing
• Solver-based refinement
• Gasket-element meshing
• Thin solid-shell meshing
• Periodic mesh matching


In this tutorial, you will learn to use the Sizing tool using Ansys Meshing. In this case, the geometry is a cube but you can apply the same in another body. With this tool you can generate localized mesh.

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.
