Compression of LS-DYNA3DTM Simulation Results using FEMZIP

Clemens-August Thole Fraunhofer Institute for Algorithms and Scientific Computing Sankt Augustin, Germany The standard usage of simulation as part of the automotive design process has increased the demand for archiving simulation results. Intensive collaboration during the development process requires the exchange of simulation results. Compression of simulation results reduces the size of archives and the time for data transfers. Like compression of video streams and pictures, the effective compression of simulation results requires specific tools which exploit the specific data structures of LS-DYNA3D simulation results and allow for a reduced precision of the results. FEMZIP is especially designed for the compression of crash simulation results and achieves a reduction by factor of 7 for reasonable precision requirements.
