12.3.12. Mesh Modification

RecurDyn/Mesher supports to modify the nodes and the elements of the mesher result.

12.3.12.1. Node Merge

This function combines two nodes and make one node. The related elements are modified. Shell3 elements are deleted and Shell4 elements are converted to shell3 elements.

Select Type
- Node: Select two nodes. Two nodes are merged.
- Line: Select one line. Two nodes of the line are merged.
- Element: Select one element. The two nodes of the shortest line of the element are merged.
Node Position
- Mid: The final node is on the middle point of the selected two nodes.

- Edge: If one of the two nodes is on the edge, the final node are on the node position of the edge.

Auto Operation
- If the entity (nodes, line or element) are selected than the merge function is applied instantly.
Revert
- All modification is canceled. It changes to the final mesh result.

12.3.12.2. Combine Shell3

The function combines two shell3 elements and creates one shell4 element.

../_images/image1176.png — Figure 12.73 **Combine Shell3 Elements** dialog box

Select Type
- Line: Select one line. Then there are two elements connected to the line. Two elements are combined.
- Element: Select two elements. Then the two elements are combined.
Auto Operation
- If the entity (nodes, line or element) are selected than the merge function is applied instantly.
Revert
- All modification is canceled. It changes to the final mesh result.

12.3.12.3. Split Shell4

This function splits one shell4 element and creates two shell3 elements.

../_images/image1206.png — Figure 12.75 **Split Shell4 Element** dialog box

Select Type
- Node: Select two nodes that belong to the one shell4 element. Then the shell4 element is split with the line of the two nodes.
- Element: Select the one shell4 element and the shell4 element is split.
Auto Operation
- If the entity (nodes, line or element) are selected than the merge function is applied instantly.
Revert
- All modification is canceled. It changes to the final mesh result.
