New Developments in the Compression of LS-DYNA Simulation Results using FEMZIP

The standard usage of simulation as part of the automotive design process and increased computer power has increased the demand on archiving resources. This data may be reused several times during the development process and reused later for new models. Compression of the simulation results reduces both the archive size and the access times. This is why FEMZIP was developed several years ago. FEMZIP was specially designed for the compression of crash simulation results. We report on the improvements of FEMZIP both in regard to speed and to compression factors. FEMZIP is now also available built into several postprocessors. This means that these postprocessors can read and process compressed files directly. As a consequence of the improvements in FEMZIP, the postprocessors can display the compressed files faster than uncompressed files.
