Durability diagnostic groups

When you select the Create Diagnostic Groups option that is available in the Durability Event Solver dialog box and the Durability MetaSolution Solver dialog box, the durability solver creates diagnostic groups that show elements that do not have sufficient durability requirements. Two types of diagnostic groups are created:

• Event diagnostic groups

• Durability diagnostic groups

These groups are stored in the Simulation Navigator under the Groups node.

Groups
1 – Durability 1–Static Event 2_InvalidMaterialPropertiesGroup_Fatigue_Saftey_Factor
2 – Durability 1–Static Event 2_InvalidMaterialPropertiesGroup_Fatigue_Life
3 – Durability 1–Static Event 2_InteriorElementsGroup
4 – Durability 1_NoEventResultsGroup_Fatigue_Saftey_Factor
5 – Durability 1_NoEventResultsGroup_Fatigue_Damage
6 – Durability 1_NoEventResultsGroup_Fatigue_Life

Example showing Groups nodes in the Simulation Navigator

The Durability solution process name appears as a prefix in the names of all the diagnostic groups. The event name is included in the names of event diagnostic groups.

The following event diagnostics groups can be created:

• [prefix]_InvalidElementGroup contains elements for which durability solver internal functions returned an error code. If you see this group, consider logging a problem report.

• [prefix]_NoMaterialGroup contains elements that do not point to any material.

• [prefix]_IgnoredElementGroup contains elements of types not supported by the durability solver.

• [prefix]_IgnoredNodeGroup contains nodes that are not processed by the durability solver because they are attached to:Beam elements.Elements that point to different materials.Elements in one of the previously mentioned groups.

• [prefix]_InteriorElementGroup contains interior solid elements. Interior elements are ignored for fatigue analysis.

• [prefix]InvalidMaterialPropertiesGroup[durability result type] contains elements that do not have the necessary material properties defined for the selected durability result type.

• [prefix]NoResultsGroup[durability result type] contains elements that do not have the necessary stress or strain histories for the selected durability result type.

The following durability diagnostics group can be created:

• [prefix]NoEventResultsGroup[durability result type] contains elements that do not have the selected durability results in all participating durability events.
