Failure Diagnostics

When meshing fails, the software gives a message and stops unless automatic trials is active. A failure diagnostics tool is provided to help you locate and resolve solid meshing problems.

The meshing of a solid component consists of two basic phases. In the first phase, the mesher places nodes on the boundary. This phase is called surface meshing. If the first phase is successful, the mesher starts the second phase where it creates nodes in the inside, fills the volume with tetrahedral elements, and places mid-side nodes. Mid-side nodes are placed only if high mesh quality is requested in the meshing Options dialog box. Failure can occur during one of the two phases.

The Failure Diagnostics PropertyManager lists and highlights the components that failed. For each component, it lists and highlights the faces and edges that caused the failure.

  • Failed Components . Lists all components that failed during meshing.

  • Status . Lists the phase in which meshing failed for the component highlighted in the Failed components box and offers possible solutions.

  • Failed Faces . Lists faces along with the associated features that caused the failure of meshing of the component highlighted in the Failed components box.

  • Failed Edges . Lists edges that caused the failure of meshing of highlighted face in the Failed faces box.

Click Tools, Check to check the model for invalid geometry.

To identify failing components:

  1. After meshing has failed, right-click the Mesh icon and select Failure Diagnostics.

  2. To identify the problem with a component, select it in the list box.

All faces and edges of the selected component that caused the meshing to fail highlight in the graphics area.

  1. To identify a failing face or edge, select it in the list box.

Selected face or edge highlights in the graphics area.

The Failure Diagnostics PropertyManager is available for solid mesh only.
