Radioss Interface 2021.1 Release Notes

Radioss Interface

New Features

Exported Decks Formatting
For the Radioss profile 2021, the format of the exported decks has been fully redefined, with the export of all solver keywords field names and the re-ordering of the keyword blocks in a more comprehensive and consistent way.
Include Organization
The Organize context menu option is now available for all entities. Furthermore, the organization of entities into an include file has been improved to automatically consider all references linked to the selected entities. This feature is also available performing drag and drop of an entity into an include file.
New Reference Geometry Entities
The Reference Geometry entity is introduced to provide a better support of the airbag reference geometry and foam reference geometry keywords. A dedicated graphical representation is used which allows the visualization of the airbag patches. The interactive modification of the nodes defining the /EREF is also possible directly on the graphic.
