Sweep Meshing for a Multibody Part

Goals

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

Importing Geometry

-Copy the multi.agdb file from the Tutorial Files folder to your working directory

-Start Workbench and double-click the Mesh entry in the Component Systems panel

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

-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.

Insert Sweep Mesh

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.

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

Edge 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

Sweep Settings

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 0.25 [cm]. Expand the Statistics entry and set the Mesh Metric to
Skewness

Initial Mesh

11.Generate the Mesh. Note the effect of the Edge Sizing and the Max Skewness

Inflating the Method

12.Inflate the Sweep Method selecting the 8 edges shown. Set the Inflation Option to Total Thickness and set 5 layers with a Maximum Thickness of 0.5 [cm].

13.Generate the Mesh. Observe the nature of the mesh and the Max Skewness.

Workshop 6.2 Thin Model Sweep

Goals

This workshop demonstrates the use of the Thin Model Sweep method for a single body with multiple elements through the thickness.It also shows how Virtual Topology can be used to convert the model to a form suitable for a normal sweep which allows bias in the sweep direction and inflation

Importing Geometry

1.Copy the thinmodel.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 thinmodel.agdb file you copied and click Open. Note that the Geometry entry in the Project Schematic now has a green check mark.

Insert Sweep Mesh

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.

7.Right-click on Mesh and insert a Method. Select the body and set the method to Sweep.

8.Set the Src/Trg selection to Manual Thin and select the three faces shown as the Source.

9.Set the Sweep Num Divs to 4
