ANSYS LS-DYNA
ANSYS LS-DYNA software can be used with the ANSYS Workbench export capability or the traditional ANSYS graphical user interface (GUI) and ANSYS Parametric Design Language (APDL). The technology is the most popular time-tested explicit solver for relatively slow-speed impact-related analysis. APDL and ANSYS Workbench interfaces isolate the user from the complex input requirements of this sophisticated solver. ANSYS LS-DYNA is the result of a collaborative effort between ANSYS and Livermore Software Technology Corporation. First introduced in 1996, ANSYS LS-DYNA capabilities have helped thousands of customers in numerous industries resolve highly intricate design issues.

ANSYS LS-DYNA supports both 2-D and 3-D explicit elements, and features an extensive set of single-surface, surface-to-surface and node-to-surface contact as well as a contact analysis option that automatically creates the contact surfaces. ANSYS LS-DYNA also gives optional methods for fast solution processing. The symmetric multiprocessing (SMP) and massively parallel processing (MMP) methods optimize the power of multiple CPUs to deliver explicit simulation results in a fraction of the time.
ANSYS Workbench Based Preprocessing
A new paradigm for managing simulations is used with the ANSYS Workbench GUI at ANSYS 12.0. The ANSYS Workbench GUI now consists primarily of a toolbox region, project schematic, tool bar and menu bar. Models setup in the other analysis system, such as static structural, can be persistently linked to an explicit dynamics system to transfer material data, mesh, connections, loads and constraints. ANSYS LS-DYNA users at ANSYS 12.0 will be able to use the Workbench base mechanical application to read in a CAD model, load, mesh and export a “file.k” for editing and solving with ANSYS LS-DYNA solver. Postprocessing can be done with the ANSYS Mechanical APDL application which has extensive time/history capabilities.
Native CAD Import and Robust Meshing
Native, bi-directional CAD connectivity and automatic meshing with advanced options are provided through the ANSYS Workbench platform . The ANSYS Workbench platform provides bi-directional CAD connectivity with major CAD systems, and allows import from most neutral geometry formats.
The ANSYS Workbench platform also provides a wide range of highly robust and automated physics based meshing tools including tetrahedral meshes, pure hexahedral meshes, mixed hex/tet/pyramid meshes, inflation layers and high quality surface meshes. Users also have the ability to control many advanced meshing options such as body, surface or edge sizing controls, sphere of influence, inflation layer meshing, mesh defeaturing tolerances and much more.
ANSYS Drop Test Module
Product drop tests present users with unique parameters for simulation and analysis. The ANSYS Drop Test Module included with ANSYS LS-DYNA and ANSYS LS-DYNA PC adds a complement of loads and conditions tailored specifically for such analyses.
