The tables below present the effects of meshing two or more bodies in a multibody part using a combination of different mesh methods:
Using combinations of surface mesh methods
Using combinations of solid mesh methods
Applying a single 3D inflation control on more than one solid body when a combination of mesh methods has been scoped to the bodies
Applying a 3D inflation control on a solid body when more than one mesh method has been scoped to the body
Note:
The Cartesian mesh method operates at the part level, and does not support interactions with other mesh methods. If one body in a multibody part is scoped to be meshed with the Cartesian mesh method, all bodies will be added to the scoping.
Refer to Conformal and Non-Conformal Meshing for information about conformal meshing.
The table below describes the automatic sequencing of surface mesh methods when two mesh methods are being used. If all four methods are being used, the automatic sequence is:
Note: If you are performing selective meshing, you control the sequence. Refer to Selective Meshing for usage notes.
| Surface Mesh Method | Surface Mesh Method | |||
|---|---|---|---|---|
| All Triangles | Quad Dominant | MultiZone Quad/Tri | Automatic (PrimeMesh) | |
| All Triangles | N/A | All Triangles first | All Triangles first | Automatic (PrimeMesh) only |
| Quad Dominant | All Triangles first | N/A | Quad Dominant first | Automatic (PrimeMesh) only |
| MultiZone Quad/Tri | All Triangles first | Quad Dominant first | N/A | Automatic (PrimeMesh) only |
| Automatic (PrimeMesh) | Automatic (PrimeMesh) only | Automatic (PrimeMesh) only | Automatic (PrimeMesh) only | N/A |
The table below describes the automatic sequencing of solid mesh methods when two methods are being used. If more than two methods are being used, the automatic sequence is:
Note:
If you are performing selective meshing, you control the sequence. Refer to Selective Meshing for additional usage notes.
During automatic sequencing of solid mesh methods when inflation has been applied, inflation is always applied last and uses as its input mesh the complete currently existing part mesh.

| Hex Dominant | General Sweep | Thin Sweep | Patch Conforming Tetra | Patch Independent Tetra | MultiZone | Automatic (PrimeMesh) | |

1–While mixing Sweep and MultiZone mesh methods, pre-meshed faces may be used in these ways:
Mapped faces can be supported as side faces when MultiZone or Sweep is used to mesh subsequent bodies. The pre-meshed faces may have been generated using either General Sweep or MultiZone. There are limitations on how the face is mapped. Simple mapped faces (that is, 4-sided) are supported. However, more complicated submapped cases may cause problems.
Mapped faces can be supported as source faces.
Free faces (where mesh does not have a quad mapped pattern) can be supported as source faces only.
The table below describes how inflation is handled if you apply a single 3D inflation control on more than one solid body when a combination of mesh methods has been scoped to the bodies.
| Method 1 | Method 2 | Supported Inflation Algorithm |
|---|---|---|
| Patch Conforming Tetra | Patch Independent Tetra | Post inflation only |
| Patch Conforming Tetra | MultiZone | Pre inflation only1 |
| Patch Independent Tetra | MultiZone | No inflation allowed; inflation is suppressed |
| Patch Conforming Tetra | Patch Independent Tetra (+ Method 3 of MultiZone) | No inflation allowed; inflation is suppressed |
| General Sweep | Any other method | No inflation allowed; inflation is suppressed |
| Thin Sweep | Any other method | No inflation allowed; inflation is suppressed |
| Hex Dominant | Any other method | No inflation allowed; inflation is suppressed |
| Automatic (PrimeMesh) | Any other method | No inflation allowed; inflation is suppressed |
1– In such cases involving MultiZone, the value of the Inflation Algorithm control displays as but an O-grid-based algorithm specific to MultiZone is used. As with the inflation algorithm, the mesh is inflated during the meshing process.
The table below describes how inflation is handled if you apply a 3D inflation control on a solid body when more than one mesh method has been scoped to the body. In such cases, the method control that appears lowest in the Tree is respected and therefore inflation is handled as it would normally be handled for that method.
| Lowest Method in Tree | Supported Inflation Algorithm(s) |
|---|---|
| Patch Conforming Tetra | Post or Pre inflation |
| Patch Independent Tetra | Post inflation only |
| MultiZone | Pre inflation only1 |
| General Sweep | No inflation allowed; inflation is suppressed |
| Thin Sweep | No inflation allowed; inflation is suppressed |
| Hex Dominant | No inflation allowed; inflation is suppressed |
| Automatic (PrimeMesh) | No inflation allowed; inflation is suppressed |
1– In such cases involving MultiZone, the value of the Inflation Algorithm control displays as but an O-grid-based algorithm specific to MultiZone is used. As with the inflation algorithm, the surface mesh is inflated first and then the rest of the volume mesh is generated.
