Diagnose AutoGEM Problems
Creo Simulate writes AutoGEM status and messages such as errors, warnings, and information to the Diagnostics dialog box. Creo Simulate highlights the elements or geometrical entities that cause a problem in the meshing. You can take a closer look by selecting individual entity or element in the Diagnostics dialog box.
When Creo Simulate encounters any problem while meshing a model, the Diagnostics : AutoGEM Mesh dialog box opens. Creo Simulate writes an error or a warning message in the Diagnostics dialog box.

If the meshing of the model completes without any problems, the Diagnostics dialog box opens to display the number of nodes and elements that are created during meshing. Creo Simulate does not count nodes that are created at the end of edges and datum curves while reporting the number of nodes.
The Diagnostics dialog box opens in asynchronous mode during the meshing process. You can not pan and zoom the model. You can not access any Creo Simulate or Creo Parametric menus. You can not save the information in the Diagnostics dialog box until the meshing stops. You can not select Info > Item Info on the Diagnostics dialog box.
If you close the Diagnostics dialog box during the meshing, Creo Simulate does not display any messages. You can view all messages after the meshing stops. To view all messages that are generated during the most recent AutoGEM meshing, first open the AutoGEM dialog box and then open the Diagnostics dialog box. To open the Diagnostics dialog box, select Refine Model > Diagnostics.
After you identify the problem, the best way to fix the geometry may be to modify the part dimensions. For example, if a hole that you intended to go through your part does not extend far enough, the part may have an extremely thin region that is not practical to mesh. Another example of geometry that can cause meshing problems is a cosmetic round with a very small radius. You can suppress these features before you analyze the part.
Pay particular attention if your model demonstrates an unexpectedly high element count for the given the geometry, or shows unusual element concentrations, which are often indicated by dense point clouds.
