LS-DYNA V971 R4.2.1 (R4.53450) released

Filed under:
New version of LS-DYNA is released for all common platforms.

Version 971 R4.2.1 includes the following updates from the previous release R4.2.

 

General

  • Change the behavior of the command line option ncpu=#.
    Case 1: ncpu=-n negative number of CPU's
            The code will always turn on the consistent option (CONST=1).
            It will override the consistency flag on *CONTROL_PARALLEL if it exists.
    Case 2: ncpu= n positive
            If there is no *CONTROL_PARALLEL, CONST=2 as default.
            If there is *CONTROL_PARALLEL, it uses the value of CONST on this card.
  • Add info when thermal linear solver 3 fails.
  • Fix MPP restart for thermal using direct solver.
  • Fixes for encrypted input: seatbelt materials, *KEYWORD inside the encrypted block, and proper handling of *COMMENT cards.

 

Airbag

  • Fix to *AIRBAG_HYBRID leakage in case where some parts have negative CP23 and don't belong to airbag being considered.
  • Disable CPM particle (*AIRBAG_PARTICLE) data output to D3THDT.
  • Change of CPM particle to fabric PV work calculation by nodal velocity instead of fabric segment average velocity.
  • Fix for CPM with MPP pre-decomposition.
  • Make molar-fraction based inflator gas inflow available for *AIRBAG_HYBRID_JETTING.
  • Implement molar-fraction based airbag inflator input for *AIRBAG_HYBRID.
  • Bug fix for treating non-closed airbag volume (MPP only).
  • Bug fix for read in *AIRBAG_PARTICLE cards and give warning message if nonlinear cp is not a monotonic function within gas temperature of operation (MPP only).
  • Add particle friction for CPM.
  • Fixed the volume calculation for control volume airbags that have holes in the mesh (MPP only).

 

ALE

  • A bug fix for ALE ambient type 5 (*LOAD_BLAST).
  • *LOAD_BLAST + ALE coupling with area weighted nodal velocity.
  • Use area weighted nodal velocity for *LOAD_BLAST + ALE coupling to avoid edge effect.

 

Constrained Options

  • Fix for *CONSTRAINED_INTERPOLATION so that division by zero is avoided when no rotational DOFs are present.
  • Fix for MPP restart with *CONSTRAINED_TIED_NODES_FAILURE.
  • Fix errors in implicit RBE3 constraints.
  • Fixed affecting staged construction models containing nodal rigid bodies and shell elements.

 

Contact Options

  • *CONTACT_2D_SLIDING_ONLY does not apply to 2D shell elements. An error message is printed at termination.
  • Fixed a problem in 2D tied contact that cause a lack of force balance when more than one tied contact appears in a model.
  • MPP fix for soft=4 contact along with adaptive constraints.
  • Bugfix in beam-to-beam contact.
  • Fix for soft=4 contact and adaptive constraints so soft=4 can be used in forming calculations.
  • Fixed a memory error when two surface force transducers are used with MPP segment based contact. The bug could cause a segmentation fault in single precision versions.
  • Corrected the airbag thickness by load curve option for segment based contact. It was offsetting the contact surface by the total thickness instead of half the thickness.
  • Added support for interference contact with segment based contact.
  • Fixed thermal work due to friction in segment based contact.
  • MPP contact damping was only being applied when nodes are approaching the surface, instead of both ways (as SMP does). This should make the behaviours more consistent, and be more stable.
  • Protect against divide by zero in new segment based contact penetration check and in new DEPTH=23 option.
  • Fixed 2 surface force transducer contact when used with segment based contact. It was possible for segmentation violation to occur.
  • Fixed 2D thermal contact. It was likely to segmentation fault.
  • Skip reporting contact time step for segment based contacts.
  • Bug fix for shell edge contact (MPP only).
  • Fix problem in reading beam node list from wrong contact definition for single surface contact (MPP only).
  • Improvements in MPP groupable contact:
    • Changes to improve stability.
    • Fixed problem whereby not all nodes were being considered in the energy calculation for groupable single surface contacts, and the sliding energy in GLSTAT was wrong.
  • SMP tiebreak surface to surface was affected by node order.
  • Possible floating point exception in groupable contacts, including AUTO_TIEBREAK.
  • Fixes to MPP groupable contact and adaptivity.
  • MPP fixes for groupable AUTOMATIC_TIEBREAK contacts.
  • Fix for MPP groupable contact interface energy calculation.
  • Fixed airbag thickness by load curve option for segment based contact (MPP only).
  • Fix some MPP initialization problems related to interface linking and tied node pairs.

 

Control Options

  • Change the behavior of the command line option ncpu=#.
    Case 1: ncpu=-n negative number of CPU's
            The code will always turn on the consistent option (CONST=1).
            It will override the consistency flag on *CONTROL_PARALLEL if it exists.
    Case 2: ncpu= n positive
            If there is no *CONTROL_PARALLEL, CONST=2 as default.
            If there is *CONTROL_PARALLEL, it uses the value of CONST on this card.
  • Disable NCPU option on *CONTROL_PARALLEL or control card 16.
    Print a warning if the user defines this option.
     *** Warning in keyword *CONTROL_PARALLEL
                 NCPU option will be obsolete and ignored in the next release

  • Added new option "NOSOL" for *CONTROL_TERMINATION (Column 6):
    • Flag for a "non-solution" run, i.e. normal termination directly after initialization (transformation, mapping, trimming, mesh check, ...).
  • Added new option for *CONTROL_ADAPTIVE.
    ADPSIZE .LT.0 - absolute value defines the minimum characteristic
                    element length to be adapted based on square root
                    of element area. i.e. instead of comparing the
                    shortest element edge with ADPSIZE, it compare the
                    square root of element area with abs(ADPSIZE)
                    if ADPSIZE is given by a negative value.
    
  • Added damping to stabilize the penalty formulation of sliding only contact.
