Altair HyperMesh 2022 Release Notes

Aeroelasticity

The following are applicable for both the OptiStruct and Nastran/MSC profiles.

Enhancements

  • The position of engine mesh can be aligned as desired using location selection and the Move tool.
  • Aeroelasticity set (AELIST) is exported in sorted ascending order of aero element IDs. It is a requirement for solvers.
  • Monitor points can be created by selecting a predefined set of sets (AECOMP).
  • The Name field is removed from microdialogs for all aeroelasticity tools to be in consistent with other tools. The name can be changed through the Entity Editor. Also, the ID field is removed for Spline, control surfaces, and monitor point tools.
  • Tool tips are provided for all aeroelastic entities and their fields through the Entity Editor.
  • Removed the Model system option from the CAERO1 Panel Mesh hamburger menu.
  • Airbus: Panel meshing using the "Panel mesh" tool is enhanced by direct selection of LCS. Also, the Move tool has been incorporated to position panes and their chord sizes before meshing. LCS can also be selected through a microdialog to define a panel in a local coordinate system. The same Move tool is used to edit and remesh panels under edit mode.


    Figure 1.
  • With the help of location selection and the Move tool, aero bodies can be positioned at the right location before meshing. The same can be repositioned under edit mode by using Move tool as well.
  • Location selection and the Move tool are now used to position monitor points.

Resolved Issues

  • A performance issue with body/panel meshing on bigger models is resolved.
  • An unexpected import warning while importing HMNAME COMP is fixed.

New Features

Post Script Removal
  • Any realization without a post script will now automatically create properties and materials dependant on the element in the body of the realization.
  • The property option "None" has been removed; it is now simplified to specify a Property/Material or leave it undefined.


    Figure 2.
  • The following realizations have had their post scripts set to No/Skip when created through Controls as they are no longer required:
    Spot Types
    • acm (detached-(T1+T2)/2)
    • acm (equivalenced-(T1+T2)/2)
    • acm (general)
    • acm (shell gap)
    Bolt Types
    • bolt (2 cylinder rigid)
    • bolt (b31)
    • bolt (cylinder bar)
    • bolt (cylinder rigid)
    • bolt (step hole)
    • bolt (threaded step hole)
    • BUSH cylinder
    • hinge
    • hinge (b31)
    Line Types
    • adhesive-hemmings
    • adhesives
    • HC mig weld
    • hexa (adhesive)
    • hexa (RBE2-RBE3)
    • rigid (crbody) HC laser
Connector Imprint Generalisation


Figure 3.
  • Rebuild is now available post imprinting for better a quality mesh.
  • Rebuild is now optionally available for the Washer if it interacts with feature edges to improve mesh quality.
  • If a Bolt connector creates a hole during realization, it can now be filled on unrealization.
Metadata Mapping from Parts
Allow the metadata on a given part to be mapped to the connector as links and metadata.


Figure 4.

Enhancements

Realizations
  • Bolt(Metal Clip) has undergone a significant upgrade:
    • The body elements can be changed within the control/connector.
    • Any change in the vector is now remembered locally on the connector with the use of the "Overwrite Attribute" flag.
    • Materials and Properties can now be selected and filtered from a default location.
    • The tower and hole elements are placed in a contact set in LS-DYNA and PAM-CRASH.
  • Hexa Imprint (adhesive contact) + Penta Imrpint (adhesive contact)
    • Contact type changed to Shell Edge to Surface in LS-DYNA.
    • Part Set is now default for the Secondary set in LS-DYNA.
xMCF
  • A new mechanism to add HyperMesh information into the xMCF format has been added under the export option "App Data Block". This will export the Connector details including the Connector Controls.
  • A new mechanism to add the Realization information into the xMCF format has been added under the export option "FEM Data Block". This will export the element types and references into the FEM Data Block. It will also add the PID of the realization.
  • Property Links historically have been converted into Component links when exporting xMCF. This has been reverted and will now directly export the links as Property References.
Workflows
  • "Create New" in the Connector tools now say "Create New/Edit" when controls exist.
  • "Create New" now creates a control if there are no controls.
  • Double clicking connectors in the Model Browser now filters the Connector Browser.
  • Instance links now shown on Attachments in the Connector Browser.
Absorption
Absorbing connectors allows the assignment of the property to the connector during the absorption process.


Figure 5.

Resolved Issues

  • xMCF Clip are now classified as a Bolt, in line with the realization types.
  • For a spot line where each spot can fail independently of the rest of the line, a "Partial Realisation Option" has been added where X% of the Connector needs to realized for the Connector to be marked realized.
  • Systems created in Spot Lines will now have the Z axis follow the Spot Line Direction.
  • Merge Lines in the Create tools now no longer require all the lines to be selected at once.
  • Attachment REM issues fixed for Attachments that are referenced.
  • Loading Parts with Connector Groups as instances was causing a crash. This has now been fixed.
  • Attachment performance has been improved with unrealizing/realizing and creation.
  • Importing a Binary or XML of Connectors or Attachments where the Part ID no longer exists was causing the UID to be lost. This has now been fixed.
  • Connector Lines/Spot Line XMLs are now independent of the pitch size. The accuracy of the shape of the line should not change when exporting/importing.
  • Connectors when realizing to a Solid mesh were selecting internal faces. They will now only realize to external faces of the Solid mesh.
  • The option to realize the internal/external face of a Solid mesh is now available. The option is on the Connectors/Controls as "Solid Outer Face".
  • When saving Attachments into a Connector Group, the Controls were not saved with the Connector Group. This has now been corrected and the controls are saved.
  • Absorbing Connectors with links that are instances of the same part will now append each instance of the part to the Connector.
  • Connector Lines/Spot Lines now have different End Offset options. The graphics have been updated to indicate directionality of the Connector.
