| During the process of triangulation, a mesh of triangular elements is created around existing nodes. This usually creates triangular elements outside the desired mesh boundary. Many of these exterior triangles are very skinny, and some are virtually invisible. The Select Thin Triangles command from the [[SMS:2D Mesh Elements Menu|Elements Menu]] finds and selects skinny triangular elements which are on the mesh boundary.

| Thin triangles interior to the mesh will not be selected when this command is performed, since deletion of interior triangles would result in gaps in the mesh. After the thin triangles have been selected, they can be removed by selecting the [[SMS:Macros|Delete macro]] [[Image:Delete.jpg]].
