LS-DYNA

LS-DYNA is a simulation program that works with the finite element method and was developed by Livermore Software Technology Corporation (LSTC), founded in 1987 by John Hallquist , on the basis of the previous program DYNA3D . In particular, non-linear and highly dynamic problems can be processed with this program. The program has found widespread use in these simulation areas, particularly because of its explicit time integration .

Meanwhile LS-DYNA also houses a powerful implicit structure solver to calculate quasi-static load cases. LS-DYNA also provides a variety of particle methods. The existing coupling of the discrete element method with the finite element method is currently a unique selling point among the commercial simulation programs.

Range of functions

Crash test simulations and other highly dynamic problems are particularly suitable areas of application . For the automotive industry in particular, LS-DYNA offers specific problem solutions such as various dummies (test mannequins) or the simulation of components such as airbags and seat belts . Other areas of application are fluid dynamics , fluid-structure interaction and simulation of manufacturing processes (in particular deep drawing , hot forming , magnetic forming and welding simulation ). Various non-linear material laws are contained in the software package, whereby you can also incorporate your own material laws using the USER routine. Almost 300 materials and their physical properties are already specified in the material library.

Third-party applications can be connected to LS-DYNA via a freely accessible interface. Both post and preprocessing are often carried out with the free LS-PrePost program, which is also developed by LSTC. Other popular products include primers from the Oasys Suite, ANSA / muETA from BETA CAE Systems SA , ParaView , HyperWorks from Altair Engineering and Animator4 from GNS. The LS-Opt program is available for optimization problems. The current version of ANSYS also provides an interface for this program.

Distributors

The manufacturer Livermore Software Technology Corporation (LSTC) does not sell the program itself in Central Europe . The German distributors of the software are DYNAmore and CADFEM.
