Ansys Meshing – Refinement

Refinement controls specify the maximum number of times you want an initial mesh to be refined. You can specify refinement controls for faces, edges, and vertices.

To insert a refinement control:

Click Mesh on the Tree Outline.

Do one of the following:

Right-click and select Insert> Refinement from the context menu.

Click Mesh Control on the Context Toolbar and select Refinement from the drop-down list.

In the Details View, scope the geometry whose mesh you want to be refined.

Specify a Refinement value between 1 (minimum refinement) and 3 (maximum refinement). If you attach several controls to the same entity, the last control applied takes precedence.

Some refinement controls can override or affect other refinement controls that have been applied to connected topology. A face refinement control overrides a refinement control on any of the face’s edges or vertices. An edge refinement control overrides a refinement control on either of the edge’s vertices. Basically, a refinement control will lower the value of an overridden control by its own value.

For example, consider a face refinement control with a refinement value of 1, where one of the face’s edges has a refinement control with a value of 2, and one of the edge’s vertices has a refinement control with a value of 2. In this example, the face refinement control reduces the value of the edge refinement control by 1, and it also reduces the value of the vertex refinement control by 1. The edge refinement control now has a value of 1, so it reduces the vertex’s refinement control by 1. Now the vertex refinement control has a value of zero, which essentially means the refinement control has no effect.


In this tutorial, you will learn to refine the mesh of a geometry using Ansys Meshing. In this case, the geometry is a hexagon but you can apply the same in another body.
