Splitting faces

Video: Clean up a midsurface in preparation for meshing

Use Split Face to divide a selected polygon face into two separate faces.

For example, you can use Split Face to:

• Add an edge to divide a face so that you can apply an edge-based load.

• Divide an irregular face into several smaller faces on which you can define mapped meshes.

• Restore an edge that was previously removed by another abstraction command, such as Merge Face or Auto Heal Geometry, or by the automatic abstraction that occurs during 2D or 3D meshing.

• Divide highly curved geometry, such as convergent geometry that is created from imported STL data, using facet edges.

Splitting faces by points or suppressed edges

You can use the Split Face command to divide a face between existing points or along a suppressed polygon edge.

• Use the Split face by points option to split a polygon face by selecting two points on one of the face's edges.

• Use the Split face by suppressed edges option to split a polygon face by restoring an edge that was previously removed by another abstraction command or process.

Splitting faces along the edges of facets

You can use the Split face by facet edges option to use a temporary facet or transient element edge to divide a face. With this option, after you select the polygon face to split, the software:

• Hides any existing mesh on that face.

• Creates a transient mesh on the face.Note: The software uses a different color to display the transient element edges.

You can then use the Select Facet Edge option to select the edges of the transient elements. The edges that you select must touch the boundary of the face in two locations.

Note:

You can use the Transient Elementselection type option in the together with the Connected Element Edges or Most Tangent Path smart selection method to specify options for selecting these element edges.

When you click OK or Apply, the software creates a new polygon edge to split the face and restores the original mesh, if applicable.

The Split face by facet edges option is particularly helpful in models that have large amounts of curvature, such as convergent polygon bodies that are created from STL data. The Split face by points option, for example, does not work well on highly curved models that may contain folded faces.

Note:

You cannot use the Split face by facet edges option to divide non-manifold faces.
