Nodes repair

Many of the mesh tools involve selecting or manipulating nodes. Ensure that the nodes in the part are visible and selectable by activating the required layers in the Layers pane.

Use the Align Nodes command to reposition nodes to lie on a straight line. You must first select the two nodes that define the straight line (alignment edge), and then select the nodes to move.

Use the Global Merge command to search the entire mesh to find and merge all nodes that are within a specified distance from each other. This distance is the merge tolerance. The Global Merge command acts on the entire mesh, whereas the Merge command acts only on the nodes you specify.

Note: In product versions 2013 and beyond, node labels are automatically 'squeezed' to ensure that nodes are labeled sequentially with no gaps in between. If you have imported a model from an older version, or from a 3rd party package and notice that the values for the node labels exceed the number of nodes, then you can use the Global Merge to squeeze the labels and thereby save computing memory and time.

Use the Insert Nodes command to split 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.

Use the Match Nodes command to project nodes from one surface of a Dual Domain mesh into the selected triangles on the other surface of the Dual Domain mesh to re-establish a good mesh match after manually fixing the mesh.

Use the Merge Nodes command to merge one or more nodes to a single node. The Merge command acts only on the nodes that you specify, whereas the Global Merge command searches the entire mesh and merges all nodes within the specified distance from each other.

Use the Move Nodes command to either move one or more nodes to an absolute location, or, move one or more nodes by a relative offset.

Use the Purge Nodes command to remove all nodes that are not connected to elements.

Use the Smooth Nodes command to create element edge lengths of a similar size for a more uniform mesh.
