Penetration Search Methods
 ‘Old’ Node-based search
(Sect. 26.6 in LS-DYNA Theory Manual [2006])
 Used by non-automatic contacts
 Not good for disjoint or irregular meshes
 Requires correct orientation of segments
 Shell thickness is optional
 Bucket Sort Approach
(Sects. 26.8.1 and 26.11 in LS-DYNA

MPP Contact
 MPP = Massively Parallel Processing (or Distributed
Memory Parallel)
 SMP = Shared Memory Parallel
 One of the main differences between MPP LS-DYNA and
SMP LS-DYNA is the implementation of the contact
algorithms.
 When the same input deck is run with SMP and MPP,
results may
