Radioss Interface 2020 Release Notes
Altair HyperMesh
New Features
- Support of Radioss 2020 Version
- New Keywords
- New keywords from Radioss solver version 2019.2 and version 2020 for /ANIM, /FAIL and /MAT keyword groups have been added.
- Support of Undefined Parameters
- Parameters which are referenced in a Radioss keyword but not defined in the input deck are maintained in the HyperMesh session and represented as undefined.
- New Friction Entity
- The new Friction entity is used to support the Radioss keyword /FRICTION which allows to define a specific friction model between parts or set of parts in contacts.
- New Loads Entities
- All Radioss loads (/BCS, /GRAV, /INIVEL, /IMPVEL,….) are migrated to new HyperMesh entities, having their own Pool-IDs which avoids ID conflicts and automatic renumbering during Radioss model import process. The new loads entities have a dedicated vector or contour display. Along with this implementation, the Radioss BCs Manager has been removed.
- New Set Segment Entity
- The old Contact Surfaces entity is now migrated to the Set Segment entity. With this migration, the /SURF/SEG Radioss keywords are now directly listed in the surface SET selection, with all other /SURF types.
Enhancements
- Updated Keywords
- Existing keywords from keywords groups /ALE, /MAT, /PROP and /RBODY have been updated regarding Radioss solver version 2019.2 and version 2020.
- Export of Keywords with Solver Field Names
- As part of a new development for the support of the solver keywords, all Radioss Material cards are now exported properly with all solver field names.
- Model Checker
- Some improvements have been made in the Radioss Model Checker: performances, checks coverage and new icons to start the model checker and perform all automatic corrections.
- Penetration Tool
- Added new "Minimum penetration depth" option to filter out penetrations having minimum depth values.
- Seatbelt System Tool
- A new feature in the Seatbelt System tool, allows to automatically generate cross-sections on the belt segments for post-processing of belt loading.
- Dummy Browser
- The dummy positioning tool supports now Radioss dummy models with /PROP/KJOINT2 joints definition.
- Remove include file reference based on export status
- HyperMesh only. When exporting a solver deck, references to any includes are always written to the master model even if the include itself is set to "Do Not Export."
- Mass Calculation
- The entity state of the Solvermass entity is now considered for the mass calculation. When it is OFF, the lumped mass added by the corresponding /ADMAS keyword is ignored.
Resolved Issues
- During model import process, the wrong Warning message referencing to the Engine file is now corrected.
- Issue fixed during deletion of Positions from the Dummy Browser.
- Some invalid checks in the model checker have been removed.
- Import warning for engine file not found has been corrected in order to appear only when it is valid.
Altair HyperGraph
Enhancements
- Reader enhancements
-
Summary Supported Format Fixed an issue with the name of acceleration components . T01
Resolved Issues
- Reading multiple T0x files when the folder path is too long.
- Reading T01 file on Linux: For some outputs, the Y components were not exposed with the correct name.
- Shell outputs given by /TH/SHELL/SX_JJ, SY_JJ correctly exposed in Y components.
Altair HyperCrash
Enhancements
- Keywords Support
- Approximately 20 keywords updated or added for Radioss solver versions 2018, 2019, and 2020.
Resolved Issues
- Correction in contact intersections detection.
- Corrections made in plies handling into laminates to expose plies solver IDs and improvements made in edition and deletion of plies.
