Workshop 6

Meshing of Static Mixerwith Sweep Methods



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

• The use of Inflation is alsodemonstrated for both the Sweepand Patch Conforming methods



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


• 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 Initial Mesh

• Double-click the Mesh entry in the

schematic or right-click and select Edit

• Expand the Geometry entry in the

Outline and note that there is a single

part with 4 bodies

• Left click on the Mesh entry and set the

the FLUENT solver

• Right click on Mesh and Insert a Mesh

Method. Select the three cylindrical

bodies from the Model View and choose

the Sweep Method

• Set the Src/Target Selection to Manual

Source and select the three end faces of

the cylindrical bodies

Workshop 6

Training Manual Patch Conforming Tetrahedrons

• 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




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).

•

Right-click


. ,

leaving the other settings at defaults.



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


-

mesh. Notice that the mesh is conformal



Workshop 6

Training Manual Inflating the Tetrahedrons Method

18. Right-click on the Tetrahedrons Method

and choose Inflate this Method. The

inflation will be scoped to the central body.

Select the 2 outer radial faces of the

conical body

19. Set the Inflation Option to Total Thickness

and set the Maximum Thickness to 0.2 m, Right-click

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.




Workshop 6

Training Manual Interior View of Inflated Mesh

22. Use a section plane to check the mesh interior. Note the conforming mesh.




Workshop 6

Training Manual What we have learned

•Automatic identification of sweepablebodies

•Settings for sweeping


•Inflation for sweeping
