Global Merge tool dialog

Use the Global Merge command to merge all nodes in the mesh that are within a specified distance from each other. This distance is the merge tolerance.

To use this tool, click (Mesh tab > Mesh Edit panel > Global Merge).

Note: Ensure that the nodes are visible and selectable by activating the required layers in the Layers pane.

Dialog element	Explanation
Merge overlapped nodes	Overlapping nodes adversely affect the quality of the mesh. Select this option to remove the overlapping nodes. The minimum distance between nodes is provided by the merge tolerance.
Merge tolerance	Enter the required minimum distance between nodes, or merge tolerance (mm). Nodes located closer together than the specified merge tolerance, are merged.
Merge nodes along an element edge only	Nodes are merged if: they are connected to the same element type and they form an element edge, OR they are not connected to the same element type. For example, one node is connected to triangular elements only, and another to beam elements only. Note: Deselect this option when using Global merge to fix free edges.
Remove duplicated beams and triangles	This option is primarily to address models that were meshed in older versions of the software and then imported, and is selected by default.
Resolve sharp triangles	Avoid very high aspect ratios, especially when the longest side is in the direction of the flow, as this can affect localized results. Select this option to resolve sharp triangles (aspect ratio > 1000:1). This option is selected by default.
Squeeze entity labels	Select this option to save on computer memory and analysis time by eliminating unused entity labels and renumbering nodes sequentially. If you select this option and deselect all others, the mesh will not be altered.
Merge report	Upon completion of a global merge, this area displays the number of nodes and elements that were moved.
Create as	This section is disabled for this dialog.
Filter	Use the filter to select a particular model or mesh entity. When you use a filter, the pointer snaps to the specified entity.
Restrict to visible entities	When Global Merge is applied, only elements on the visible layer are affected. Deselect this option to apply Global Merge to the whole model.
