What is meshing in ANSYS?
Meshing is the process of turning irregular shapes into more recognizable volumes called “elements.” Before you start meshing, you must first upload a geometry or CAD model into, for example, Ansys Mechanical to begin the simulation process.
What are the different types of meshing in ANSYS?
ANSYS FLUENT can use meshes comprised of triangular or quadrilateral cells (or a combination of the two) in 2D, and tetrahedral, hexahedral, polyhedral, pyramid, or wedge cells (or a combination of these) in 3D. The choice of which mesh type to use will depend on your application.
How should I decide which mesh to use in ANSYS?
Choosing a suitable mesh size
- Perform chosen analysis for several different mesh sizes.
- Notice where high deformations or high stresses occur, perhaps it is worth to refine mesh in those regions.
- Collect data from analysis of each mesh: outcome, number of nodes in the model, computing time.
Why mesh is used in ANSYS?
Ansys meshing capabilities help reduce the amount of time and effort spent to get to accurate results. Since meshing typically consumes a significant portion of the time it takes to get simulation results, Ansys helps by making better and more automated meshing tools.
Why do we need meshing?
Why is meshing important? Meshing is one of the key components to obtaining accurate results from an FEA model. The elements in the mesh must take many aspects into account to be able to discretize stress gradients accurately.

Which mesh type is best?
If the accuracy is of the highest concern then hexahedral mesh is the most preferable one.
