SMS:Merge 2D Meshes

Two meshes can be merged to form a new mesh which will be called "Merged" (or something similar if that name is already used)in the Project Explorer. No model data will be transferred, and the type of the new mesh will be the same as the default mesh model set in the user Preferences regardless of the model type of the meshes used in the merge. (To check the user preferences, go to Edit|Preferences... and check the Startup tab). This option is accessed by selecting two meshes and right-clicking and then selecting Merge 2D Meshes.

A merged mesh will be generated if and only if the meshes do not overlap except on nodes and element edges that are on the border of the other mesh. Overlapping element edges can only be on the border of the mesh and must have nodes at the same location. Disjoint nodes of one mesh that are inside the area of the other mesh will cause the merge to be prevented. A pair of meshes are also invalid for merging if the centroid of an element in one mesh is within the area of an element in the other mesh.

Examples of Meshes that will merge

Example 1: Mesh cells that can merge because they share the same element edge and nodes.	Example 2: Mesh cells that share the same node and do not overlap can be merged.
Example 3: Mesh cells that can merge because they do not overlap.

Examples of Meshes that will not merge

Example 1: Mesh cells that will not merge because they are overlapping.	Example 2: Mesh cells that will not merge because they overlap and do not share the same element edges and nodes.	Example 3: Mesh cells that will not merge because they do not share the same nodes in the same location.
Example 4: Mesh cells that will not merge because they do not share the same nodes.	Example 5: Mesh cells that will not merge because a disjointed node of one mesh is with in the area of the second mesh
