3.4 Local Mesh Controls

Local mesh controls are available when you highlight a Mesh object in the tree and choose a tool from
either the Mesh Control drop-down menu, or from first choosing Insert in the context menu (displayed
from a right mouse click on a Mesh object). You can specify the scoping of the tool in the tool's Details
View under Method to either a Geometry Selection or to a Named Selection.
The following local mesh controls are available:

3.4.1 Tetrahedrons Methods Group

The Method control is valid only for a body. The default value selects meshing methods that provide a
successful automated mesh. By default, the application attempts to use auto sweeping for solid models
and quadrilateral element generation for surface body models. If a model is not sweepable, the Patch
Conforming mesher under Tetrahedrons is used.

To set the values for the Method control, click Mesh on the Tree Outline, right-click to view the menu,
and select Insert> Method. You can also click Mesh on the Tree Outline, select the Mesh Control button
on the Context Toolbar, and select Method.

Mixed order meshing is supported across bodies for the following mesh methods: For solid meshing:

w Patch Independent Tetrahedron
