To split elements by inserting nodes

Insert Nodes splits an existing triangle or tetrahedral element into smaller elements by inserting a new node either midway along an edge of a triangle, or in the center of a triangle or tetrahedron.

Note: Insert Nodes only works if the selected nodes all belong to the same element.

1. Click (Mesh tab > Mesh Edit panel > Insert Nodes).
2. Select where you want the new node to be created:
   • Midpoint of triangle edge - select the two nodes that define the triangle edge.
   • Center of triangle - click in the center of a triangle to select it.
   • Center of tetrahedron - click in the center of a tetrahedron to select it.
   • Middle of beam element - select a beam element and enter the number of divisions you want to create.
3. If the mesh nodes are not visible, turn on the relevant layer(s) in the Layers pane.
4. Click Apply to insert a new node at the specified location. New element edges are created to split the existing element into smaller ones.
