Get LS-DYNA Software

LS-DYNA® from Livermore Software Technology Corp. (LTSC) is the world's most advanced general-purpose nonlinear finite element program. It is capable of simulating complex real-world problems, and is widely accepted as the premier analysis software package for today's most challenging engineering applications.

At Predictive Engineering, we are longtime experts in LS-DYNA and can help guide you through the software acquisition process, installation, support and user training.

 

LS-DYNA can predict how a prototype will respond to real-world events such as crashes, drops, earthquakes, bird strikes and more. The ability to simulate these events in software minimizes the time and expense that must be devoted to experimental testing.

The applications of LS-DYNA are numerous, from understanding automotive collision effects to predicting stresses and deformations in metal forming processes to bird strike and failure analysis in aerospace.

Applications

Auto crashworthiness & occupant safety

  • Accurately predict behavior in an automotive collision. Includes specialized features for seatbelts, slip rings, pretensioners, retractors, sensors, accelerometers, airbags and Hybrid III dummy models.

Aerospace analysis

  • LS-DYNA is widely used by the aerospace industry to simulate bird strike, jet engine blade containment and structural failure.

Sheetmetal forming

  • Accurately predict stresses and deformations experienced by metal in processes such as stamping, hydroforming, forging and deep drawing. LS-DYNA supports adaptive remeshing and will refine the mesh during the analysis, as necessary, to increase accuracy and save time.

Supported Platforms

LS-DYNA is well optimized on all platforms including multiprocessor platforms (see table below). Its accuracy has been proven through extensive correlation with experimental data and, of course, analytical solutions. LS-DYNA is an invaluable tool for capturing extreme nonlinear events where other solvers have failed.

Performance

LS-DYNA runs on leading PCs, Unix workstations, supercomputers and MPP (massive parallel processing) machines.

Computer resource requirements vary depending on problem size. Simulations with more than 100,000 elements have been run using 15 million words of memory and 100 Mbytes of disk space. On super-computers, the code is highly vectorized and takes advantage of multiple processors.
