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.
  • 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.

Browsers

Enhancements

Massive performance improvements
Around 70% reduction in time for data population in the Model, Include, Subsystem, and Solver browsers, which improves overall model load time.


Figure 2.
Embedded EE in Create/Edit dialog
The embedded Entity Editor is now supported in the Create/Edit dialog for quick editing of referenced entities, which avoids navigation to different pages.
Parameter context menu
All the parameter context menu options are now grouped under a "Parameter" category for ease of use.


Figure 3.
Restoring of browser on invoke
All browsers that were open in previous session are now restored at once and tracked by the status bar.

Resolved Issues

  • Performance issue while invoking Includes and Subsystem browsers.
  • Performance issue with populating Nodes and Elements in browser.
  • "Add Metadata" option was missing for certain entities.
  • Entity Editor would go blank on editing reference entity ID.
  • Crash on selecting temp nodes with regular nodes.

Known Issues

  • Entity Editor is not cleared when entity is removed from filtered browser list.
  • Collected entities are not updated correctly upon making the respective collectors inactive.

Certification

Enhancements

Back-end engine improved to support element_nodes and result averaging
  • Method manager provide options while authoring method template to allow corners and average.
  • When created, methods have "Average mode" & "Use corners" options that you can change in HyperMesh for various evaluations.
  • Averaging applies to result data types only, not model attributes.


    Figure 4.
  • Result nodal queries (such as displacement) are available and can be mixed with element data (model or result).
    • Nodal results are transferred to element.node value on each element attached to a node.

      No division/average happens.

      • This is valid for displacement results but invalid for nodal forces. Instead, use gridpoint force directly with corner "on".
    • If a model attribute bounded to an element (area/volume..) is run with nodal results, it is spread to each node and a method is evaluated per node (per element).
    • If a result attribute is bounded to an element with a layer (along with nodal result), then the nodal value is spread to each layer and a method evaluated per element.layer.node.
    • If element results have corners (and method has corners "true"), then nodal results can be mixed the with element corner values.
    • If average mode is used, element results are first averaged to node (with or without corners) then spread to node of element (corner) to run a method per element.(layer).node.
    • Whenever element & nodal results are mixed, use the engine enforce system for extraction in Global to keep data consistent.
      • Note that "Analysis system" is usually different for elements and nodes. The back-end engine was improved to support element_nodes and result averaging.
      • A warning message is posted in the Run report. For more information, see the log file.


        Figure 5.
Run method on elements
  • Methods can be evaluated on FE elements directly without creation of designpoint and designpointset.
  • This is valid if method inputs does not require structural property and if there is no sorting defined that implies aggregation across elements.
  • A new option is added to select the system for component extraction.
    • In the event of averaging or nodal result being used by a method, the system will switch to the global system.


    Figure 6.
Structural Element detection
  • New Split option in Panel & Generic Structural Element detection
    • split by element's property
    • split by element's component
  • For panels, the split is performed after topology detection. If 1D are used with shell, then panels are first detected, then split applies to detected panels.


    Figure 7.
Structural Property made optional
  • Run is no longer prevented for designpoints without structural property.
  • First ply failure method can now run on panels without structural property.
    • The engine will then collect elemental properties directly to evaluate a method per element.
    • If a structural property is applied, then the assigned property takes precedence over the element's property for all elements in the same panel.

Known Issues

In method contour, it is possible to select "nodeids" result on nodes (or corners). This will result in a nodal contour with unique values on nodes.
  • If results where saved as corner data (node of element), then the displayed contour is the aggregated value.
  • Aggregation follows the general Sort key (min|max|absmin|absmax ) in contour UI already used whenever an aggregation happens (accross loadcases or layers).


    Figure 8.

Resolved Issues

  • Fixed issue when multiple freebodysections referring to the same elements where used.
    • Results used to be saved against elementID (so values were lost for some freebodysections).
    • Result structurse now account for entityID.elementID. where entityID is freebodysection ID.

      For non-entity based methods (bounded to element), the table shows an entityID the same as the designpoint ID.

Composites

New Features

Filament Winding Workflow
  • Through ply types, filament winding simulation data from APA software can be directly imported. Zone based properties per element are no longer used or required.
  • Filament winding data is displayed and can be reviewed for each winding angle.
  • Models can be directly solved in OptiStruct and post-processed using .h3d data.


Figure 9.

Known Issues

General
  • Laminate and ply edit performance for large models. A workaround is to stack a ply with no shape temporarily in the laminate.
  • Detailed thickness review with ply layers of Wound ply type does not take drape data into account correctly. This fix will be in 2022.1.
  • Import performance of filament wound models with more than ~150k elements

Resolved Issues

General
  • Performance of mass calc for models with many laminates
  • Laminate realization segmentation error when unsupported element types passed
  • Spreadsheet import of multiple sets only tool first set ID in list
Composite Stress Toolbox
  • Running laminate engineering constants analysis with n sub-laminates of the same interface laminate would lead to n-times the zones of the interface laminate to be shown in the results. Now they are only shown once.
  • Filtering would malfunction for laminate reserve factor for mixed failure criteria (plies and wrinkling) in certain circumstances.
  • Load response analysis for laminates with plies of type “Shell to Solid Layer Divider” would crash.

Connectors

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.

    • 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.

  • 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.

Geometry

New Features

FE Geometry
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry is to add vertices, edges, surfaces, & solids on FE models which have no CAD geometry. Tools and workflows operate similarly on CAD and FE. With FE geometry, mesh selections are made easier as they are topology-based selections. FE geometry can be used for 1D and 2D elements. It is recommended to use FE geometry where there is no CAD associated to mesh.
Unsplit
New HyperWorks Unsplit workflow added to remove split lines so split surfaces return to their original unsplit state.

Enhancements

  • Geometry can be created as CAD geometry or FE Geometry by setting create mode under Geometry preferences.
  • Most of the geometry creating and editing tools have been instrumented to support FE geometry. This allows use of CAD editing tools on elements.
  • Autocleanup functionality is supported fully under Defeature – Batch tool.
  • Sketch - Intersect tool now supports intersection of 2D and 3D elements while creating reference plane.

    • Improvements on patch algorithm to avoid patch failures
    • Enhanced defeaturing of fillets
  • Updated workflow help showing new options supported by geometry tools.

Resolved Issues

  • Fixed robustness issues related to Sketch, Drag, Imprint, and Cross Extend tools.

Known Issues

  • If a solver deck is imported with the Create FE geometry option "on", or a portion of the model is converted to FE geometry, HyperMesh post functionalities are lost. You need to delete the FE geometry present in the model before proceeding to HyperMesh post-processing.
  • Assign plot contour is not supported for FE geom elements in the Check Elements (F10) 1D & 2D panel.

Matrix Browser

Enhancements

  • Multiple result queries can be executed while in the Matrix Results Query dialog without the need to reopen the dialog.
  • Macro recording supports HyperMesh result queries.

  • You can now choose to populate the entity query ID column in an increasing or decreasing order. By default, the entity IDs are returned in the order they have been generated in the HyperMesh database.
  • Matrix settings have been moved to the Post section of the general Preferences dialog.

Resolved Issues

  • Certain integer type data names were previously reported as floating values. They are now correctly returned as integers.

Meshing

New Features

Associate Tool
New context-based workflow added for nodes and elements association in the Elements ribbon, Edit Elements tool. This tool helps you detect and graphically review associated and non-associated nodes, perform local association, disassociation, and correction of wrong association.
Mesh Controls
Mapped Mesh and Edge Biasing local control newly added under Surface mesh. Mapped control along with Edge biasing helps you get structured mesh on four sided faces.

  • Face mesh control updated with Layers option. This helps with creating a specific number of layers on selected faces, either constant size or stretched.
  • Added option to controlthe number of mesh affected layers for CAD/FE geometry topology editing, such as split and unsplit. This option can be set from the meshing preferences.
  • Added Quad only and R-Trias element type option for solid map.
  • Thickness mapping tool ignores surfaces associated to target mesh.

Once the positioning is completed, you have direct visual feedback with the target points entity graphics on the positioning accuracy of the dummy.

Enhancements

Mechanism Constraints
The existing Constraints entity used in the Mechanism tool is renamed to Mechanismconstraints entity. This allows for using the Constraints entity as a solver entity.

Skeleton Modeling

New Features

Introduction of Skeleton Modeling
The skeleton modeling functionality provides a mechanism to create a reduced ordered model to facilitate optimization at the concept phase.
A skeleton model can be derived from several different sources. The most common sources are donor FE and CAD geometry. All the sources shown in the image are supported, including direct interpretation from topology results.


Figure 18.
The skeleton model build process is dissected into three key stages – Joints, Members, and Panels. The image below shows the source input, the skeleton model build phase, and then the reduced order skeleton model.
