This file is revision 0 of the release notes for LS-DYNA version 7.1.1.
----------------------------------------------------------------------------
Herein are summarized several bug fixes made since the
now withdrawn release of version R7.1.0.
____________________________________________________________________________
Fix definition of ANSYS library for userlib.
Fix softening of *MAT_BRITTLE_DAMAGE/*MAT_096 behavior caused by typo in r86847.
This fixes bug 9596.
Fix error in handling of *CONTROL_REQUIRE_REVISION.
Fix problem with parameter SCLMRR of *DEFINE_CONNECTION_PROPERTIES.
New encryption keys now in effect. There are
two, a 1024 bit key and a new 2048 bit key.
The 2048 bit key has a bit of a performance hit
during keyword input, so should be generally avoided.
*DATABASE_JNTFORC outout broken by r86847 checkin.
Fix problem generating *RIGIDWALL visualization nodes
if beam orientation nodes are also generated.
Fix MPP memory overwrite during *DATABASE_BINARY_INTFOR initialization
that could have caused a segmentation fault.
Fix bug and clean up d3thdt output (*DATABASE_BINARY_D3THDT) for SPH.
Fix memory problem while using *BOUNDARY_SPH_SYMMETRY_PLANE option -- MPP only.
Fix output of *INITIAL_STRESS_SHELL to dynain for MPP when using
staged construction. Broken at r86856.
MPP spotweld deletion: better handling of bad user input.
A spotweld node should not be defined as slave to more than one
tied interface. If it is, it gets deleted from all but one
of them. Previous code would delete the spotweld if the
slave node of any interface reported the slave node not tied
and SPOTDEL was active. Now only delete the spotweld if
ALL interfaces in which it appears report it as not tied.
This fixes bug 9469.
Fix tied node checking in MPP for the IPBACK
flag that affected non-groupable tied contacts.
This fixes bug 9414.
MPP: synchronize rigid body flags for shared nodes
during *DEFORMABLE_TO_RIGID switching so that these
nodes are handled consistently across processors.
Fix SMP bug that causes too many opened files
in problems with many many adaptive steps: a file
was being opened every cycle but not closed.
This fixes bug 9420.
