Refinement control 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 access the Refinement Control,
On the Tree Outline, right-click Mesh and click Insert > Refinement.
Or
On the Tree Outline, click Mesh and click Refinement in the Mesh Context tab on the Ribbon.
Or
Right-click a face, edge, or vertex, and then select Insert > Refinement
The Refinement Details View has the following options:
Scope
Scoping Method: Allows you to scope geometry or named selection. The default value is Geometry Selection.
Geometry Selection: Allow you to scope the geometry bodies. When you select Geometry Selection, the Geometry allows you to select the geometry from the Geometry window.
Named Selection: Allow you to scope bodies grouped under a named selection.
Definition
Suppressed: Allows you to suppress the method control. The default value is No. When Suppressed is set to Yes, the Active provides the number of suppressed parts and is a read-only option.
Refinement: Specify the maximum number of times you want an initial mesh to be refined. The default value is 1. You can parametrize Refinement. When you define multiple entities, the last applied refinement control 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.
Note:
Refinement controls are not available for the MultiZone, Patch Independent Tetra, Cartesian, Layer Tetrahedron or MultiZone Quad/Tri mesh methods. If you are using the Automatic Method and you have enabled the Use MultiZone for Sweepable Bodies option, refinement controls on sweepable bodies behave similarly to how they behave when the Sweep mesh method is used.
Refinement controls are automatically suppressed with following scenarios:
When automatic inflation (either Program Controlled or All Faces in Chosen Named Selection) is used with refinement in the same model.
When local inflation is used with refinement in the same body or in the same part.
If you apply a refinement control to a part that was either swept meshed or hex dominant meshed, and then you delete the refinement control, the intermediate tetrahedral mesh is retained unless you invalidate the state of the part (for example, by clearing the database). An intermediate tetrahedral mesh is created when you try to refine non-tetrahedral solid elements.
Refinement controls are not supported on shared faces between solid bodies and sheet bodies in a multibody part.
Refinement controls are not supported for Mixed Order Meshing.
Special processing of refinement operations occurs when you use the Mesh worksheet to create a selective mesh history. Refer Using the Mesh Worksheet to Create a Selective Meshing History for details.
