ANSYS Discovery SpaceClaim

Removing small faces

The Small Faces tool detects and removes small and sliver faces in your design. You may want to remove these faces before you export the design for analysis if they will have a negligible impact on the analysis accuracy but a significant impact on its speed.

If the small face is tangent to a neighboring face, the tool will merge the small face with the neighboring face. If no neighboring face is tangent, the tool will extend neighboring faces to remove the small face.

To remove small and sliver faces

1. Click Small Faces in the Adjust group of the Repair tab.

   The tool automatically finds small faces in the active component and highlights them in the design area, as shown in the image above.

2. Select the object(s) you want to change:

3. Set the Maximum area and Maximum width in the Options panelArea of the user interface that enables you to modify functions specific to tools.. Faces that are smaller than the maximum area and thinner than the maximum width will be found and highlighted for adjustment.

4. Use the controls in the Navigate ribbon group to view each problem one at a time before you fix it.

   • Click Next or Previous to step through and highlight each identified problem.

   • Select Zoom to Fit if you want to automatically zoom in on the problem in the design area when you click Next or Previous.
