SMEARED_PROPERTIES: For regions with composite section assignments, the density is smeared across the thickness. The volume centroid and center of mass computations for a composite shell use a lumped mass approach where the volume and mass is assumed to be lumped in the plane of the shell. As a result of these approximations the volume centroid, center of mass and moments of inertia may be slightly inaccurate for regions with composite section assignments.

INCORRECT_MOMENT_OF_INERTIA: For geometry regions with non-structural mass per volume, the non-structural mass is assumed to be a point mass at the centroid of the regions. Thus, the moments of inertia may be inaccurate as the distribution of the non-structural mass is not accounted for. Use the mesh for accurately computing the moments of inertia.
MISSING_BEAM_ORIENTATIONS: For some regions with beam section assignments, the beam section orientations are missing.
UNSUPPORTED_BEAM_PROFILES: This method supports the Box, Pipe, Circular, Rectangular, Hexagonal, Trapezoidal, I, L, T, Arbitrary, and Tapered beam profiles. Any other beam profile is not supported.

This method copies a mesh pattern from a source region consisting of a set of shell elements or element faces onto a target face, mapping nodes and elements in a one-one correspondence between source and target.
Required arguments
Optional arguments
A sequence of MeshElement objects or a Set object containing elements and specifying the source region.
A sequence of Face objects that have associated with shell elements or element faces and specifying the source region.
A sequence of MeshFace objects specifying the source region.
A MeshFace object specifying the target region.
A sequence of MeshNode objects or a Set object containing nodes on the boundary of source region which are to be positioned to the boundary of target face.
A sequence of three-dimensional coordinate tuples specifying the coordinates for each of the given nodes. When specified, the number of coordinate tuples must match the number of given nodes, and be ordered to correspond to the given nodes in ascending order according to index. These coordinates are positions of the nodes of a mesh that will be the target face corresponding to nodes provided.
Return value
Exceptions
This method smoothes the given nodes of a native mesh, moving them locally to a more optimal location that improves quality of the mesh
Required arguments
Optional arguments
A sequence of MeshNode objects or a Set object containing nodes. Nodes that are not part of native mesh only will be smoothed

The Part object has members with the same names and descriptions as the arguments to the Part method.
In addition, the Part object can have the following members:
A Boolean specifying the validity of the geometry of the part. The value is computed, but it can be set to ON to perform feature and mesh operations on an invalid part. There is no guarantee that such operations will work if the part was originally invalid.
An Int specifying that feature parameters have been modified but that the part has not been regenerated. Possible values are 0 and 1.
A Float specifying when the part was last modified.
A VertexArray object specifying all the vertices in the part.
An IgnoredVertexArray object specifying all the ignored vertices in the part.
An EdgeArray object specifying all the edges in the part.
An IgnoredEdgeArray object specifying all the ignored edges in the part.
A FaceArray object specifying all the faces in the part.
A CellArray object specifying all the cells in the part.
A repository of Feature objects specifying all the features in the part.
A repository of Feature objects specifying all Feature objects in the part. The Feature objects in the featuresById repository are the same as the Feature objects in the features repository. However, the key to the objects in the featuresById repository is an integer specifying the ID, whereas the key to the objects in the features repository is a string specifying the name.
A repository of Datum objects specifying all the datums in the part.
A MeshElementArray object specifying all the elements in the part.
A repository of MeshFace objects specifying all the element faces in the part. For a given element and a given face index within that element, the corresponding MeshFace object can be retrieved from the repository by using the key calculated as (i*8 + j), where i and j are zero-based element and face indices, respectively.
A MeshFaceArray object specifying all the unique element faces in the part.
A MeshNodeArray object specifying all the nodes in the part.
A MeshNodeArray object specifying all the retained nodes in the substructure part.
A repository of Set objects specifying the contents of the allSets repository is the same as the contents of the sets repository.
A repository of Set objects specifying picked regions.
A repository of Surface objects specifying the contents of the allSurfaces repository is the same as the contents of the surfaces repository.
