Created using SIMULIA V6 R2013
The Sweep 3D mesher allows you to mesh a solid geometry by sweeping an existing surface mesh from a source face to a target face. This tool can be found in the Advanced Meshing workbench of SIMULIA V6. It is commonly used in ExSight.
To generate a sweep mesh, the volume must be assimilated to a prism with a top (Target) and a bottom (Source). The curves joining the top and bottom surfaces are called guide curves. The faces between guide curves are called lateral guides.
You can mesh the geometry with hexahedron and/or wedge elements (linear or parabolic). When possible, neighboring lateral and top meshes are captured to provide a solid mesh without interference. The mesh is extruded from a source surface (containing the surface mesh) to the target surface.
A workflow to generate a sweep mesh is given below.
Annotated Video
The following demonstration includes:
-Surface extraction (0:00-1:00)
-Surface mesh creation (1:00-3:00)
-Sweep mesh creation (3:00-5:00)
-Mesh quality analysis (5:00-6:40).

Note
This is one of the workflows to generate a sweep mesh.
For example, there is an alternative workflow that does not require the initial extraction of the source surface. In this case, while creating the surface mesh, you select the entire geometry (default), i.e., the support for the surface mesh includes all exterior surfaces of a part and not a single face of the solid geometry. In order to select only a single face for the surface mesh,
(1) Modify the support from the Surface Mesh dialog box,
(2) Choose the desired surface, and
(3) Activate the complimentary mode in the Modify Geometry Support dialog box, as shown below.
