LS-DYNA 是世界上最着名的通用显式动力分析程序，能够模拟真实世界的各种复杂问题，特别适合求解各种二维、三维非线性结构的高速碰撞、爆炸和金属成型等非线性动力冲击问题，同时可以求解传热、流体及流固耦合问题。在工程应用领域被广泛认可为最佳的分析软件包。与实验的无数次对比证实了其计算的可靠性。
ANSYS LS-DYNA结合了工业界公认最佳的有限元素前后处理器、採用显性（explicit）非线性结构模拟能力。自1996年上市以来，ANSYS LS-DYNA的能力与强健性，帮助上千名使用者解决工业界中许多的非常难解的问题。
短时间内的现象，例如：严重的碰撞、叶片的拘束，与大变形，例如：冲压与成型，带给工程师独特的模拟挑战。ANSYS LS-DYNA藉着使用LSTC的LS DYNA显性动态求解技术与ANSYS的前后处理能力，来满足这些挑战。这有力的组合帮助工程师了解在汽车测试、金属成型、板金冲压中複杂的非线性现象。
ANSYS LS-DYNA可同时支援2D与3D显性元素，具备非常完整的单一表面，面对面与点对面的接触部分，不但有接触分析选项，而且能自动建立接触面。ANSYS LS-DYNA也提供快速求解流程的选项。对称多项式处理法（Symmetric Multiprocessing, SMP）与大量平行处理法（Massively Parallel Processing, MMP）最佳化多CPU系统的处理性能，可在短时间内完成显性模拟的结果。
因为ANSYS LS-DYNA是根据与ANSYS Multiphysics相同的高级技术所建立，所以非常容易地与其他ANSYS的产品结合，可根据个人的需要作修改。例如，可将落下试验模组（Drop Test Module）整合成一个易於使用的GUI介面来模拟动态撞击。将ANSYS Structural或是ANSYS Mechanical与ANSYS LS-DYNA结合，则具有全面的结构模拟能力。

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.
