FEMZIP and DIFF-CRASH

The software packages FEMZIP and DIFF-CRASH are further developed and marketed by our spin-off SIDACT GmbH in Bonn.

FEMZIP

Simply compress efficiently: FEMZIP compresses data from crash simulations in the car manufacturing industry as precisely as the user specifies. This reduces the total amount of data, yet important information is not lost and is still available after the decompression.

DIFF-CRASH

DIFF-CRASH is a software package for the stability analysis of collision simulators. Physical bifurcations in automobile design and numerical instabilities in simulation packages cause in many cases, an extremely sensitive dependence of the simulation results on even the smallest of model variations. DIFF-CRASH enables one to locate critical structural regions and makes suggestions on how to stabilise them.
