Expand selection to all triangles on the same surface

Use the Triangles on Same Surface tool to select all triangular elements on the same surface.

Use this tool, for example, to select all triangular elements on the same surface before applying boundaries condition, or editing a surface. The elements are selected if there is connectivity, even if the properties of the elements are different.

Note: A surface is defined by elements connected with a smooth bend angle. Elements with different properties can be part of the same surface.

The Triangles on Same Surface tool is supported for the following mesh types:

• Midplane
• Dual Domain

1. Make sure that the relevant layers are visible. Invisible triangles are not selected
2. Select a surface mesh element.
3. Click (Mesh tab > Selection panel > Expand to ...) and select Triangles on Same Surface from the drop down menu.
