Enhancements

Auto Contact update
Feature angle based individual contact surface detection is now set as default contact detection.
Updated keywords
  • *RIGID BODY – The reference node is updated with an option to reference a node set.
  • *COUPLING – A node set can be used for the reference node when type is element based surface.
  • *CONTACT FORMULATION – Support for SMALL SLIDING with SLIDING FORMULATION in general contact.
Additional enhancements
  • Support of *AMPLITUDE curve inside *STEP definition.
  • MAX1D – Axisymmetric membrane element is supported in Standard 2D profile.
  • Up to 8 nodes of an element is written in the same line upon export of input file.
  • Export option for *SURFACE to be exported in list format for elements.

Resolved Issues

  • PARAMETER dependency on other PARAMETERS and reconciling issue is fixed.
  • Element configuration was changing when profile is changed from standard to explicit and it is now resolved.
  • Beam section CENTROID, SHEAR CENTER data that are improperly imported is now fixed.
  • An include file containing data lines under *FILM was not exporting, and the issue is resolved in this version.
  • A *COUPLING node with surface type as node will be lost and this issue is fixed.
