Delete Entities

Use (

) to delete geometric entities from a mesh, as seen in Figure 8-48.

Figure 8-48: A boundary (blue) is deleted from a mesh.

To add a node, select the entities to delete in the window, then choose one of the following:

•

Right-click in the window to open The Graphics Context Menu and select (

•

Click (

) on The Mesh Toolbar.

•

Right-click node and select (


	Note that deleting entities modifies the number of geometric entities in the mesh. Thus when you are adding this operation to a meshing sequence that is conforming with the component’s geometry, a new meshing sequence that is defining its own geometric model is automatically created, and the Delete Entities node is added to this new sequence. For more information, see The Mesh Node.

Enter the properties for using the following sections:

Geometric Entity Selection

Define the geometric entities that you want to delete. You choose the geometric entity level from the list: Choose , , , or to specify the domains, boundaries, edges, or vertices, respectively, that you want to delete or choose a named selection to refer to a previously defined selection. Use , , , or to select all entities of the specified dimension.

Keep as Unmeshed Domains

In 3D, when is set to , select (cleared by default) to only delete the domain elements while keeping the domains as unmeshed as well as keeping the adjacent meshed boundaries. Use the Free Tetrahedral operation to fill any unmeshed domain with tetrahedral elements.

Adjacent Entities

Select the check box to also delete the adjacent entities of lower space dimensions.
