Mesh Mating Conditions dialog box

Type
Creation method	Selects the method to use to create the mesh mating conditions.Choose Automatic Creation to have the software automatically search selected geometry for qualified face pairs. Choose Manual Creation to manually select source and target faces to create face pairs.
Selection
Select faces or bodies	Appears when the creation method is Automatic Creation.Lets you select the bodies that the software should search for overlapping faces. Note that if you use this option to select a face, the software automatically selects the body to which that face belongs.Note: If you want to create mesh mating conditions only between selected faces, you must select Manual Creation from the creation method list.
Body Focus****Select Body	Lets you select a polygon body on which to focus.All other polygon bodies are made translucent and unavailable for further selection, so you can more easily select faces from the selected body.
Select Source Face	Appears when the creation method is Manual Creation.Lets you select the source face of a face pair.
Select Target Face	Appears when the creation method is Manual Creation.Lets you select the target face of a face pair.
Parameters
Mesh Mating Type	Specifies the type of mesh mating condition:Glue Coincident — If two faces are geometrically identical, the software merges the two faces to create a single face that is shared by the two bodies. Only the nodes on the source face remain.Glue Non-Coincident — Creates multi-point constraint equations or constraint equations to connect the nodes on the source face to the nodes on the target face.For Nastran only, creates an RBE3 connection mesh when the mated faces are meshed.Free Coincident — Aligns the nodes at the interface between the source and target. This creates a coincident mesh (with duplicate nodes) with no connection between the source and target surfaces.See Types of mesh mating conditions for more information.
Face Search Option	Controls how the software searches for face pairs.All Pairs — Finds all face pairs, both coincident and non-coincident, within the specified Distance Tolerance.Identical Pairs Only — Limits the search to coincident face pairs only (pairs in which the source and target faces are geometrically identical) within the specified Distance Tolerance. Choose this option if you want the software to imprint the source mesh onto the target mesh when it creates the mating condition.
Search Distance	When you select Automatic Creation from the Type list, specifies the minimum allowable distance between the faces of a pair.Note: If the software's internally calculated body facet tolerance is greater than the tolerance you specify in this field, the software automatically adjusts the Search Distance.
Reverse Direction	Reverses which side of the mesh mating condition is dependent if RBE3s or multi-point constraint equations are required. In general, this only applies to Glue Non-Coincident type mating conditions. However, the software may generate RBE3s or multi-point constraint equations with a Glue Coincident type mating condition if it connects HEX8 to TET10 elements and pyramid elements are not used for the transition.
Preview	(Auto Create method only) Highlights identified face pairs before creating the mesh mating condition. If the results are not what you expect, you may want to adjust the distance tolerance or change the face search option and try again, or use the Manual creation method.
