SMS:Element Patch Workflow

To create an element patch from an existing mesh, do the following:

1. Define area of mesh where the patch will be applied.
Using the Create Nodestrings tool, create nodestrings enclosing the area to be patched. The nodestrings do need to create an enclosed area without any gaps. Four nodestrings are used to patch a paved area; three nodestrings are used to pave a patched area.

2. Convert section of mesh to the Map module.
Using the Select Nodestrings tool, select the nodes strings Select the Data | Mesh→Map command In the Mesh→Map dialog, select the Nodestrings → Arcs option Click on Create New Coverage In the New Coverage dialog, select Mesh Generator. Click OK to close the Mesh→Map dialog

3. Generate mesh with patch elements.
Build polygons in the new Mesh Generator coverage Set appropriate options on the polygons Generate a mesh from the coverage

4. Merge meshes.
Select the original mesh and the new mesh in the Project Explorer Right-click on the selected meshes and choose the Merge 2D Meshes command.
