Activity: Size the mesh on a surface

Open the file FE_bearing_surf_size.par.

Simulation models are delivered in the \Program Files\UDS\QY CAD 2022\Training\Simulation folder.

Mesh the bearing:

1. Make sure Static Study 1 is the active study.

2. Choose Simulation tab→Mesh group→Mesh.

   

   Note:

   In the absence of loads and constraints, you cannot solve the study, but you can mesh the model.

3. In the Tetrahedral Mesh dialog box, select the Show Mesh option, and then click the Mesh button.

   After a short period of time, the bearing displays with a tetrahedral mesh.

   

4. Rotate the part so you can view the rear, and zoom in on the main bore.

   

Change (refine) the surface sizing:

1. Observe the current mesh on the top of the bearing bore.

   

2. Choose Simulation tab→Mesh group→Surface Size.

   

3. Select the outer cylindrical surface of the bore.

   

4. In the Surface Size dialog box, type 10 in the Element size box and click Accept.

   

5. Mesh the part again; note the increase in the element size on the selected face.

   Note:

   You can increase the size of the elements when lower accuracy is warranted on a face. This can result in faster processing.
