Sweep Meshing for a Multibody Part

Workshop 6.1

Sweep Meshing



Training ManualGoals

This workshop demonstrates the use of a sweep method for a multibody partand shows how edge sizings can be used to specify the mesh gradationin the sweep direction. It also demonstrates inflation for a swept mesh.

Training ManualImporting Geometry

1. Copy the multi.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

3. Right-click on Geometry in the

Mesh entry in the Project

Schematic and select Import

Geometry/Browse

4. Browse to the multi.agdb file

you copied and click Open.

Note that the Geometry entry

in the Project Schematic now

has a green check mark.

5. Double click the Mesh entry in

the Mesh object on the Project

Schematic

6. Close the Meshing Options

Panel at the right without setting

anything.

*Note: If you are using ANSYS V14.0 or more recent

versions of ANSYS then you will not see the Meshing

Options panel at the start of ANSYS Meshing. You will still

be able to set the Physics Preference and insert any Mesh

Methods manually or set your defaults from

Tools>Options..>Meshing

7. Right-click on Mesh and insert a

Method. Select both bodies and

set the method to Sweep.

8. Set the Src/Trg selection to

Manual Source and select the

two faces shown as the Source

Insert Sweep Mesh

Training ManualEdge Sizing

9. Define an Edge Sizing for the 2 edges shown with 20 Hard Divisions. Set the

Bias Type to shrink towards the ends and set the Bias Factor to 4

10. On the Mesh Options, set the Physics Preference to CFD and the Solver

Preference to Fluent. Turn off the Advanced Size Function and set an Element

Size of 0.5 [cm]. Expand the Statistics entry and set the Mesh Metric to

Skewness
