Workshop 6
Training Manual Goals
• This workshop will illustratecombining the Patch ConformingTetrahedrons and Sweep
Methods for a multibody part toyield a conformal mesh withhybrid tet/prism and hex elements

Workshop 6
Training Manual Specifying Geometry
• Copy the sm.agdb file from the tutorial
files folder to your working directory
– You can also continue working within the
Static_mixer.wbpj you created in theprevious Workshop
• Start Workbench and double-click the
Mesh entry in the Component
WS6-3ANSYS, Inc. Proprietary © 2009 ANSYS, Inc. All rights reserved.
• Right-click on Geometry in the Mesh
entry in the Project Schematic and
select Import Geometry/Browse
• Browse to the sm.agdb file you
copied and click Open• Note that the Geometry entry in the
Project Schematic now has a green
check mark indicating that geometry
has been specified
The first 9 steps repeatthe process followed forWorkshop 4 and 5.

Workshop 6
Training Manual Inflating the Sweep Method
• Right-click on the Sweep Method and
choose Inflate this Method. The inflation
will be scoped to the three source faces
• For the boundary, you will need to select
the three outer circular edges of the
faces (you may need to enable the Select
Edges toggle to simplify this).

Workshop 6
Training Manual Initial Mesh (no Inflation)
• Expand the Inflation entry in the Mesh
settings and set the Use Automatic tet
Inflation option to None as you will
manually inflate the two different
methods
Make sure the mesh settings are as
shown at right

Workshop 6
Training Manual Generating the Mesh
20. Generate the mesh. Note that the
swept regions still produce hexes
while the central body produces
prisms and tetrahedrons.
21. Verify that all meshes are conformal
and save your project.
