Static Mixer with Patch Conforming Tetrahedrons and Sweep Methods

Goals

-This workshop will illustrate combining the Patch Conforming Tetrahedrons and Sweep Methods for a multibody part to yield a conformal mesh with hybrid tet/prism and hex elements

-The use of Inflation is also demonstrated for both the Sweep
and Patch Conforming methods

Specifying Geometry

1.Copy the sm.agdb file from the tutorial files folder to your working directory

2.Start Workbench and double-click the Mesh entry in the Component
Systems panel at the right

3.Right-click on Geometry in the Mesh entry in the Project Schematic and select Import Geometry/Browse

4.Browse to the sm.agdb file you
copied and click Open

5.Note that the Geometry entry in the Project Schematic now has a green check mark indicating that geometry has been specified

Initial Mesh

7.Double-click the Mesh entry in the schematic or right-click and select Edit

8.Expand the Geometry entry in the Outline and note that there is a single part with 4 bodies

9.Left click on the Mesh entry and set the Physics preference to CFD and select the FLUENT solver

10.Right click on Mesh and Insert a Mesh Method. Select the three cylindrical bodies from the Model View and choose the Sweep Method

11.Set the Src/Target Selection to Manual Source and select the three end faces of the cylindrical bodies

Patch Conforming Tetrahedrons

12.Right click on Mesh and Insert a Mesh Method. Select the central conical bodies from the Model View and choose the Tetrahedrons Method with the Patch Conforming Algorithm

Initial Mesh (no Inflation)

13.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

14.Right-click on Mesh and generate the mesh. Notice that the mesh is conformal
