Table of contents
The diagnostics tools show more detailed information about the problems listed in the Mesh Statistics report.
The panel (Mesh tab 
Mesh Diagnostics panel) contains the following diagnostics to check the mesh:
| Panel item | Use this diagnostic to... | Supported mesh type |
|---|---|---|
 Aspect Ratio Diagnostic | Locate elements that have an aspect ratio above a specified limit |   |
 Beam L/D Ratio Diagnostic | Locate cooling channel elements that are too short or too elongated |  |
 Overlapping Elements Diagnostic | Locate elements that overlap or intersect, and therefore occupy the same space | |
 Orientation Diagnostic | Locate elements whose top/bottom sides are defined inconsistently | |
 Connectivity Diagnostic | Locate elements that are not connected to the rest of the mesh | |
 Free Edges Diagnostic | Locate element edges that are not shared, which may indicate gaps or holes in the mesh | |
 Collapsed Faces Diagnostic | Locate places where opposite faces of a plane share a node, and so have zero thickness | |
 Dimensional Diagnostic | View model dimension values | |
 Thickness Diagnostic | Check that thickness values in the mesh are set correctly | |
 Occurrence Number Diagnostic | Check that occurrence numbers in the mesh are set correctly | |
 Zero Area Element Diagnostic | Locate very small element | |
 Dual Domain Mesh Match Diagnostic | Check that there is a good correspondence between the elements on each side of a Dual Domain mesh | |
 Beam Element Count Diagnostic | Locate cooling channels meshed with insufficient elements | |
 Trapped Beam Diagnostic | Locate beam elements that are too close together | |
 Centroid Closeness Diagnostic | Locate triangle elements that are too close together | |
 Cooling Circuit Diagnostic | Check that each cooling circuit has only one inlet and outlet | |
 Bubbler/Baffle Diagnostic | Check that bubblers and baffles are modeled correctly | |
Topics in this section
- Checking the mesh before analysis
After meshing the model, it is strongly recommended that you perform a series of diagnostic checks to ensure that the mesh is suitable for analysis.
- Mesh statistics
Once the visual inspection has determined the mesh density looks right, use the Mesh Statistics report to determine if the quality of the mesh is acceptable.
- Mesh statistics report
The Mesh Statistics report is divided into a number of different sections that provide a quick overview of various characteristics of the mesh.
- Using Mesh Diagnostics tools effectively with large models
There are five mesh diagnostic tools that can be used for diagnosing problems with the mesh.
- Connectivity problems in the mesh
Some imported models (particularly STL models) include sections which are not connected to the rest of the model.
- Zero area elements
Zero area elements are very small elements in the mesh. If these exist, they are reported in an error message.
- Beam element diagnostic
There are several diagnostic tools related to potential beam element problems.
- Cooling circuit diagnostic
The cooling circuit diagnostic is used to check that the cooling circuit has been modelled correctly.
- Bubbler/Baffle Diagnostic
The Bubbler/Baffle Diagnostic tool is used to check whether bubblers and baffles present in the cooling circuit model are modeled correctly.
- Dual Domain and Midplane diagnostics
These diagnostic tools are specific to Dual Domain or Midplane analysis types.
- 3D diagnostics
These diagnostics are specific to 3D analyses only.
