RADIOSS Interface 2019 Release Notes

Altair HyperMesh

New Features

New Keywords
An estimated 50 new keywords are added in this HyperMesh version and enhance the Radioss keywords support.
New entity type for Accelerometers
The /ACCEL keyword was originally mapped to the Sensor entity type, but is now mapped to an independent entity, with its own IDs, icon and graphics.
New entity type for Mass
The /ADMAS keyword was originally supported as elements, but is now mapped to an independent entity, with its own IDs, icon and graphics. A specific graphic review for /ADMAS/TYPE5 is also available to review the nodal mass distribution. Along with this development, all /ADMAS types are now supported in HyperMesh.
New entity type for Elements Clusters
/CLUSTER keywords are now supported in HyperMesh, and are mapped to an independent entity, with its own IDs, icon and graphics.
New entity type for Failure Models
/FAIL keywords were originally mapped to the Property entity type, but are now mapped to an independent entity, with its own IDs and icon.
New entity type for Optimization keywords
Optimization keywords are now supported in HyperMesh inside the Optimization browser, and are treated as special entities. The optimization keywords are imported and exported in the Radioss .radopt file.
New entity type for Rigid Walls
/RWALL keywords were originally mapped to the Group entity type, but are now mapped to an independent entity, with its own IDs, icon and graphics.
New entity type for Positions and Transformations
/TRANSFORM keywords were originally mapped to the System Collector entity type, but are now mapped to an independent Transformation entity. Additionally, the Position entity is introduced as a collector of the Transformation entities that are applied to the same content.
Support of Submodels
//SUBMODEL keyword is now supported in HyperMesh. ID offsets rules and transformation rules on submodels are also implemented. All sets of type SUBMODEL are also supported.
Support of XELEM elements
/XELEM elements are newly implemented in this HyperMesh version.
Creating transformations and positions
Create Transformation and Position entities more seamlessly using the Create and Edit Position/Transformation tool, which replaces the previously existing Transformation Manager.
New Mass Summary browser
The Mass Summary browser was added to enable you to review model mass, center of gravity, and inertia details.

Enhancements

Updated keywords
An estimated 40 keywords are updated regarding the latest 2017 and 2018 Radioss solver versions.
/BEGIN card enhancement
The definition of the unit systems in the /BEGIN card support has been improved for a better user experience. The support of /BEGIN cards in Include files is also improved.
/TH card enhancement
The definition of the output variables into /TH keywords is now given as a list selection.
Material features added into compatible materials
Material features keywords (/EOS, /LEAK/MAT, /THERM_STRESS, /VISC/PRONY) were originally mapped to the Property entity type, but the definition of these keywords is now directly implemented into their compatible material keywords using the Entity Editor.
Composites modeling enhancements
Composites modeling now supports the usage of the new Radioss composites keywords introduced into the Radioss 2017 version.
Review SETs graphically
Improvements have been made for the review of SETs based on the type of set. For example, a /GRNOD/PART will highlight the nodes of the referred components instead of highlighting the components.
Accurate mass calculation
The mass calculation logic has been improved to match the solver behavior.
Penetration check enhancements
The Penetration Check tool now enables you to check Radioss Interface TYPE24. Additional improvements have also been made in the penetration’s calculation for second order elements.
Model Checker enhancements
The Model Checker infrastructure and functionalities have been improved for a better user experience.
New checks have also been added to the Model Checker.
Importing sets of subtype /SUBSET and /PART
Sets of subtype /SUBSET and /PART are not imported as a formula set when all referenced subset or part IDs are positive.
Removed tools
The following tools, previously accessible in the Tools menu and Utility browser, are removed from HyperMesh: Set Browser, Create Part, Clone Part, Material Table, Component Table.
Tools that were once available in the Utility browser are moved into the Tools menu.
Manage the printing of HyperBeam messages
An import option has been added to enable or disable the printing of HyperBeam messages. By default, this option activated and HyperBeam messages are not printed.
Find entities attached to components
The Recursive option has been added in the Find Connectivity tool to help you isolate and find entities attached to selected components. This new functionality will also help you to automatically find parts until all connected parts are found.

Resolved Issues

  • Could not create or import multiple /FVMBAG/MODIF cards defined in the engine file.
  • Could not read /MAT/LAW60 with a number of functions less than 5.
  • Sets of type GENE are created incorrectly in the Entity Editor.

Altair HyperView

Enhancements

Updated Femzip version
Femzip version updated to v8.73.

Resolved Issues

  • RADIOSS Animation (Annn) files are locked after being read into HyperView.
  • RADIOSS result files cannot be imported when the ALTAIR_FILE_DELAY_DESTRUCT environment variable is set.

Altair HyperCrash

New Features

Replace part by pairing
The Replace Part by Pairing tool has been added, and can be accessed from the Part context menu in the Model browser.

Enhancements

Element orthotropy orientation review
The display of orthotropy orientation now considers the delta_phi angle defined in /PROP/TYPE19.
Updated keywords
Multiple keywords have been updated and added to support the RADIOSS 2017.2 and RADIOSS 2018 versions.
Model Checker checks
Multiple new checks are added to enhance the Model Checker for RADIOSS.

Resolved Issues

  • Keep RBODY ID when slave nodes are modified.
  • Set nodal time step scale factor to 0.67 per default for the dummy pre-simulation.
  • Mass calculation for parts with /PROP/TYPE51.
  • Issues with /MAT/GAS conversion during /MONVOL/COMMU to /MONVOL/COMMU1 conversion.
  • Accuracy of penetrations check for interface TYPE7 with solid elements.
  • Issue with creating duplicated solid elements after a model merge operation.
  • Issue with /ADMAS/3 code when iflag=0.
  • ID offsets are not considerd for the ID ranges in /GRNOD/GENE when defined into //SUBMODEL. This behavior is managed by an option in the Preferences.
