Radioss Interface

New Features

New Radioss 2026 Profile
A new Radioss profile has been added for 2026.
New Generic Impact Workflow
The new Generic Impact tool can be used to define impact points on any type of structural parts, automatically position any type of impactors, and automatically export ready-to-run solver decks. For more details, see the Safety Tools release notes.
For example, Figure 1 shows multiple impact simulations on a door trim using a spherical impactor.

Enhancements

New Keywords Supported
The following keywords are now supported: /FAIL/FRACTAL_DAMAGE and /GAUGE/POINT.
Enhanced Keywords
The following keywords have been enhanced:
  • The Icontrol attribute has been added in the following keywords: /DEF_SOLID, /PROP/TYPE6, /PROP/TYPE14, /PROP/TYPE20, /PROP/TYPE21, and /PROP/TYPE22.
  • New Ifail_so values have been added in /FAIL/JOHNSON.

  • A new Ip=26 attribute value has been added in /PROP/TYPE9, /PROP/TYPE10, /PROP/TYPE11, and /PROP/TYPE16.
  • RbodyIDs in /PROP/TYPE15 is now a node selector.
  • The Main_ID2 attribute has been added in /INTER/SUB.
  • The output variable names in /TH/CLUSTER have been corrected.
  • New Irem_gap and Irem_i2 attributes have been added in /DEFAULT/INTER/TYPE19.
  • A new Inacti value has been added in /INTER/TYPE24.
  • New output variables VX,VY, and VZ have been added in /TH/PART and /TH/SUBS.
  • The number of mue and alpha attributes have been increased to 10 in the definition in /MAT/LAW42.
  • The new Seed attribute has been added in /FAIL/ALTER.
  • The Tension attribute has been updated in /MAT/LAW88.
  • A new Ikin attribute and Iflag value have been added in /MAT/LAW87.
  • Multiple new attributes have been added for compaction mode in /MAT/LAW50.
  • /MAT/LAW2 is now selectable in /MAT/LAW51.
  • The material selection filter has been updated in /PROP/TYPE11, /PROP/TYPE16, /PROP/TYPE19, and /PLY to allow the selection of all compatible material models.
Seatbelt Tool
Creation of /SLIPRING/SHELL is now available from the Seatbelt tool. Right-click the control point and select Slipring 2D from the context menu.
Creation of a full-meshed slipring has been enhanced using an embedded simulation for robust and high quality results.

Airbag Folder Tool
The following enhancements have been made to the Airbag Folder tool:
  • New vertical zig-zag folding has been added.
  • New diagonal tuck folding has been added.
  • New rolling folding has been added without the usage of a rolling-tool model. Instead, it is driven by user inputs on the tool shape.
  • The method to define opening in tuck folding has been improved.
  • Z-translation for simple fold and rolling has been added.
  • The definition of rigid regions for inflator insertion has been enhanced.

Resolved Issues

  • Solvermasses defined on a set of assemblies are now correctly considered in mass/COG/MOI calculation.
  • The termination time value generated by the Engine File Assistant has been corrected.
  • /FRICTION keywords are no longer detected as unused.
  • String length to define the stress file name in /STATE/STR_FILE has been corrected to a maximum of 100 characters.
  • At the end of the Bus Rollover workflow, the curve defining the gravity load is now correctly assigned to the /GRAV keyword.
