Strategies for Using the Volume Option
The following are some strategies you can follow to use Volume more effectively:
• If the boundary processing stage takes too long, interrupt AutoGEM.
• If AutoGEM has not created a full set of elements on the volumes you selected, you can try one or more methods listed in Create a Full Set of Elements.
• Volume can be very sensitive to increasing the minimum face and edge angles above 5
on the dialog box, especially for complex parts. Sometimes, increasing the minimum face angle a couple of degrees can result in many more tetrahedral elements and take much longer to complete.

Sometimes, increasing the minimum face angle a couple of degrees can result in many more tetrahedral elements and take much longer to complete.• AutoGEM can handle multiple volumes that share common surface regions. When you use Volume, select all volumes at the same time.
• If you want to create elements for a thin region, for example, sheet metal, use the Settings tab on the AutoGEM Settings dialog box to select wedges, bricks, and tetrahedrons as the elements for AutoGEM to use. For parts that have both thick and thin regions, AutoGEM uses wedges, bricks, and tetrahedrons and automatically creates links where required.
• If you are working with an assembly that fails to mesh, use > 
Tolerance Report to check the component tolerances to make sure that they are close enough. If not, return to Creo Parametric and click > > 
Model Properties to open the Model Properties dialog box. Click change adjacent to Accuracy to change the accuracy values of any component whose tolerance appears to be too high.
