Ansys LS-DYNA

 Ansys LS-DYNA is the world's most renowned general explicit dynamic simulation software that integrates finite element method and pre- and post-processing procedures, gaining high recognition and a good reputation within the industry. It can simulate different complex problems in the real world and is especially suitable for solving the short-term severe deformations of two-dimensional and three-dimensional non-linear structures, such as high-speed collisions, explosions, and large-scale permanent deformations – like stamping, metal forming, and other non-linear dynamic impacts. It can also solve heat transfer, fluid, and fluid-structure interaction problems simultaneously. Having LSTC’s LS-DYNA explicit solver closely integrated with Ansys pre-and post-processing procedures, it is more convenient and quicker to solve the virtual collision testing, Metal forging, stamping processing, breakage, and other non-linear phenomenon and their combined problems. Thus, it is widely considered as the best analysis software package in the engineering application field, having its calculation reliability proven countless times through experiments. Ansys LS-DYNA is a dedicated tool for non-linear time response analysis (such as dropping and collision), which is different from the finite element analysis tool of the implicit solver, since it uses an explicit solver that does not require convergence calculations, enabling it to process highly non-linear problems, such as dropping, collision, stamping, forging, and cutting. Engineers can conduct material failure simulations and check how cracks are generated within the materials or in between the parts and how they lead to failures. It is also easier to handle models with a large number of interactive parts or curved surfaces and to accurately simulate the power transmission between complex behaviors. Ansys LS-DYNA can effectively use multi-core resources which would reduce the computing time for the solution.

  • Ansys Workbench LS-DYNA
Ansys Workbench LS-DYNA has integrated LS-DYNA into the Workbench environment, gaining all the advantages of standardized Ansys Mechanical workflow. This means that it is integrated with the geometry tool Ansys Spaceclaim Direct Modeler, Ansys Parameter Manager, and Ansys optimization tool, allowing you to execute a complete parameter study without the need to learn the interface of a new product and only focus on the generation of accurate analysis results in a shorter period.

WB LS-DYNA Interface

 

  • Rich elements, contact, and calculation methods
Ansys LS-DYNA offers you all kinds of low-order and high-order element formulations for solids, shells, and beams, which can be applied separately through the Ansys Mechanical interface, allowing you to only place the elements of high-fidelity in necessary areas.
LS-DYNA’s wide contact options can achieve automatic contact detection between solids, shells, and beams, while also taking the cross-section of the beams and the thickness of the shells into consideration. Contacts between the sole parts, in each part, or within a single element can also be detected. Thus, a simple and stable contact can be conducted in the entire model. The calculation methods include ALE, DEM, and SPH.
