ANSYS LS-DYNA

Combine the premier software package for explicit nonlinear structural simulation with one of the industry's most recognized and respected finite element pre- and post-processors, and you get ANSYS LS-DYNA, the result of a collaborative effort between ANSYS, Inc. and Livermore Software Technology Corporation. First introduced in 1996, ANSYS LS-DYNA's capabilities and robustness have helped thousands of customers in numerous industries resolve highly intricate design issues.

Limited-duration events (such as severe collisions and blade containment) and large, permanent deformations (within the stamping and forming industries) present engineers with unique simulation challenges. ANSYS LSDYNA meets these challenges by fusing LSTC's LS-DYNA explicit dynamic solver technology with the pre-/post-processing power of ANSYS software. This powerful pairing helps engineers understand the elaborate combinations of nonlinear phenomena found in crash tests, metal forging, stamping and catastrophic failures.

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.

Because ANSYS LS-DYNA is created from the same powerful technology as ANSYS Multiphysics, it is easy to combine with other ANSYS products and tailor to your specific needs. For instance, you can incorporate the ANSYS Drop Test Module for an easy-to-use GUI for simulating dynamic impacts. Add ANSYS Structural or ANSYS Mechanical into your ANSYS LS-DYNA package for comprehensive implicit structural simulation capabilities.
