SDMZIP further improves the compression of FEMZIP by eliminating data redundancy from data sets and storing commonalities in a central database.

SDMZIP can be used for the compression of simulation results

  • one after another or
  • all at once.

The graph shows an ENCAP frontal crash robust analysis with 24 simulations using SDMZIP for an all at once compression.

The result is a significant reduction in storage space with the FEMZIP compression rate being improved by a factor of three.


Common information is centrally stored once only instead of being redundantly stored in each simulation.

If a data base, which is to be extended, is already available at one location, only the update and the specific data need to be transferred to that location, to make data available at different sites.
