Align Mesh

At times it is desirable to have identical meshes on two different surfaces or curves. The align mesh command will attempt to assign correspondence between nodes on surfaces or curves and move the nodes on one surface or curve to match the configuration on the other. The command syntax is:

Align Mesh Surface <id> [CloseTo] Surface <id> [Tolerance <tol>]

Align Mesh Curve <id> [CloseTo] Curve <id> [Tolerance <tol>]

These two commands align the mesh on the first entity with that of the second entity. This means that nodes on the first entity will be moved to the closest location possible to their corresponding nodes on the second entity. This is done without regard to mesh quality, so it is possible to invert elements with this command.

Align Mesh Node <id> [CloseTo] Node <id> [Tolerance <tol>]

This command aligns the first node with the second node, within the limits of the geometric entities that own the nodes. This is also done without respect for element quality.

And example of this is given as follows:
