If it is negative then ur contact issues are there either u have to increase contact stiffness or change the parameters again it depends on various things. LS-DYNA is an advanced general-purpose multiphysics simulation software package developed by the Livermore Software Technology Corporation (LSTC). While the package continues to contain more and more possibilities for the calculation of many complex, real world problems LS-DYNA Hybrid version is the executable which combines SMP parallel programming and MPP parallel programming paradigms. The SMP parts uses OpenMP language for thread parallelization; The MPP portions uses Message Passing Interface [MPI] language for process parallelization. LS-DYNA Theoretical Manual.

The 13th National Conf. z Experience with LS-Dyna for Dynamics Modeling. — CAE Associates' engineers have nearly 30 years of experience using explicit dynamics finite element — Over-penetration of one body into another — Excessive run times — High hourglass energies — Initial contact penetration — Solution instabilities LS-DYNA is a general purpose finite element code for simulating complex structural problems, specializing in nonlinear, transient dynamic problems using explicit integration. LS-DYNA is one of the codes developed at Livermore Software Technology Corporation (LSTC). Availability and Restrictions. You'll need to load the base LS-DYNA module to use MPP-DYNA on the cluster. In most cases this is the only module you'll need to load. We also have version-specific modules for each version of MPP-DYNA. LS-DYNA simulations are typically carried out on high-performance computing (HPC) clusters based on industry-standard hardware connected by a private high-speed network. The main benefits of clusters are affordability, flexibility, availability, high-performance and scalability.
