Chapter 3: diagnostics/

diagnostics/face-connectivity/

Contains options for fixing problems with face connectivity on the specified object face zones or boundary face zones.

diagnostics/face-connectivity/add-label-to-small-neighbors

Separates island object face zones from all connected neighbors and merges them to the connected neighboring face zone label based on minimum face count specified.

diagnostics/face-connectivity/fix-deviations

Fixes deviations in the wrapped surface mesh by imprinting edges on the wrapped face zones. Specify the number of imprint iterations and aggressive imprint iterations to be performed.

diagnostics/face-connectivity/fix-duplicate-faces

Removes duplicate faces.

diagnostics/face-connectivity/fix-free-faces/

Removes free faces by the method selected. The methods available are:

diagnostics/face-connectivity/fix-free-faces/delete-free-edge-faces

Removes free faces having the specified number of free edges.

diagnostics/face-connectivity/fix-free-faces/delete-fringes

Removes free face fringes based on the face count specified.

diagnostics/face-connectivity/fix-free-faces/delete-skewed-faces

Removes free faces based on the minimum skewness specified.

diagnostics/face-connectivity/fix-free-faces/merge-nodes

Removes free faces by merging nodes within the tolerance specified.

diagnostics/face-connectivity/fix-free-faces/stitch

Removes free faces based on the tolerance and number of steps specified.

diagnostics/face-connectivity/fix-invalid-normals

Fixes invalid normals by smoothing.


Note:  Zone-specific or scoped prism settings should be applied prior to using this command.


diagnostics/face-connectivity/fix-islands

Deletes groups of island faces based on the absolute face count specified.

diagnostics/face-connectivity/fix-multi-faces

Fixes multiply connected faces by a combination of deleting face fringes, overlapping faces, and disconnected faces. Specify the maximum number of fringe faces, overlapping faces, and multiply connected edges, respectively.

diagnostics/face-connectivity/fix-point-contacts

Fixes non-manifold configurations by removing point contacts.

diagnostics/face-connectivity/fix-self-intersections

Fixes self intersecting or folded faces. For fixing folded faces by smoothing, specify whether features should be imprinted.

diagnostics/face-connectivity/fix-slivers

Fixes faces based on skewness and height criteria. Height is the perpendicular distance between the longest edge of the triangle and the opposite node.

diagnostics/face-connectivity/fix-spikes

Fixes spiked faces based on the spike angle specified.

diagnostics/face-connectivity/fix-steps

Fixes step configurations by smoothing or collapsing faces based on the angle and step width specified.

diagnostics/face-connectivity/remove-label-from-small-neighbors

Removes disconnected island object face zone labels by merging the specified island object face zones to the connected neighboring face zone label based on minimum face count specified.

diagnostics/manage-summary

Allows you to manage the contents of the diagnostics summary (to be printed to the console using the perform-summary command. You are presented with a collection of prompts for diagnostic tests that you can include in or exclude from the summary. For instance, you can determine whether or not to check the face quality, set the maximum face skew limit, check the cell quality, check for free faces, check face self proximity, check isolated cells, and so on. By default, all diagnostic test prompts are set to yes, with the maximum face skewness limit is set to 0.99, the minimum cell orthogonal limit is set to 0.01, and the maximum aspect ratio limit is set to 10000.

diagnostics/modify-defaults

Allows you to change the default values for the number of plot partitions (from 10), the automatic delta range (set to 0.05), and the clip cluster view factor (set to 1).

diagnostics/perform-summary

Generates a mesh diagnostics summary and prints it to the console. The level of detail in the printed diagnostic summary is controlled by the manage-summary command, however, by default, the summary includes surface and volume mesh details such as the total number of faces, maximum skewness, minimal cell orthogonal limit, maximum aspect ratio, and so on.

diagnostics/quality/

Contains options for fixing problems related to surface mesh quality on the specified object face zones or boundary face zones.

diagnostics/quality/collapse

Collapses bad quality faces based on area or skewness. For collapsing based on face area, specify the maximum face area and relative maximum area. For collapsing based on face skewness, specify the minimum skewness and feature angle. Additionally, specify the number of iterations and whether the boundary should be preserved.

diagnostics/quality/delaunay-swap

Improves the surface mesh by swapping based on the minimum skewness value and feature angle specified. Additionally, specify the number of iterations and whether the boundary should be preserved.

diagnostics/quality/general-improve

Improves the surface mesh based on aspect ratio, size change, or skewness. Specify the minimum quality value, feature angle, number of iterations, and whether the boundary should be preserved.

diagnostics/quality/smooth

Improves the surface mesh by smoothing. Specify the number of smoothing iterations and whether the boundary should be preserved.

diagnostics/set-scope

Allows you to define the extent of the meshing diagnostics. You can choose to set the diagnostics scope to selected objects or not, and specify corresponding face and cell zones as needed.
