Triangle

  The Triangle option allows you to select three locations to create a triangle. A triangular element is a surface element. If not possible, a message will be displayed that it could not create the triangle because the volume mesh could not be made consistent.

Method
From nodes

allows you to elect the nodes of the mesh to define new elements. A mesh must be loaded so that nodes can be selected.

From points

allows you to select the points of the geometry to define new elements. A geometry file must be loaded so that points can be selected.

From screen

allows you to select any arbitrary location by clicking on the screen.

Make Volume Consistent

automatically adjusts the volumetric elements to conform with the new element(s). This only applies when creating triangles within a tetra mesh.

Automatic element creation

automatically creates the element after selecting the point, node, or edge, without requiring confirmation by pressing the middle mouse button.
