GWeld (Generalized Weld)

Purpose:

*CONSTRAINED_GENERALIZED_WELD has many variants in LS-DYNA, but this interface is specifically for showing, creating, modifying, and deleting *CONSTRAINED_GENERALIZED_WELD_SPOT cards. Failure parameters can be set as desired and used for the welds being created. Also these parameters can be modified as necessary for each weld.
  • Show : Show existing *CONSTRAINED_GENERALIZED_WELD_SPOT entities.

  • Cre : Create new *CONSTRAINED_GENERALIZED_WELD_SPOT entities.

  • Mod : Modify existing *CONSTRAINED_GENERALIZED_WELD_SPOT entities .

  • Del : Delete existing *CONSTRAINED_GENERALIZED_WELD_SPOT entities.

  • Label : Select label type.

  • EditPara : Click to view and edit weld parameters.

  • WID : Enter genweld optional ID.

  • NSID : Enter Node Set ID.

  • NewId : Set NSID to next highest, avaialble ID.

  • All : Select all Constrained GWeld entities.

  • None : Deselect all Constrained GWeld entities.

  • Rev : Reverse selection.

  • AList : Select all entities within the selected range (Only applies when there are 20+ entities).

  • Apply : Apply entries for creation/modification or selections for deletion.

Click button "EditPara" to view and edit parameter of *CONSTRAINED_GENERALIZED_WELD_SPOT:

  • CID : Enter coordinate system ID.

  • FILTER : Enter number of force vectors saved for filtering.

  • WINDOW : Enter time window for filtering.

  • NPR : Enter number of individual nodal pairs.

  • NPRT : Print option for RBDOUT (see LS-DYNA keyword manual for details).

  • TFAIL : Enter failure time for constraint set.

  • EPSF : Enter effective plastic strain at failure.

  • SN : Enter normal force at failure, only for brittle failures.

  • SS : Enter shear force at failure, only for brittle failures.

  • N : Enter exponent for normal force, only for brittle failures.

  • M : Enter exponent for shear force, only for brittle failures.
