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.

Data Compression

In an effort to improve engineering design larger and more detailed models as well as an increasing number of simulations are performed, yielding a steady growing amount of data. This simulation data has to be analyzed, exchanged among engineers and archived for future reference and re-analysis. Network connections and storage space can then become bottlenecks in workflows used by engineers. The challenge is to handle these large amounts of data in a time- and storage-saving manner in order to eliminate the bottlenecks.

With our FEMZIP compression tools we provide a solution to meet this challenge. FEMZIP tools are specifically designed for the compression of simulation results of various simulation codes. The high compression factors that can be obtained by employing FEMZIP lead to several benefits:

Reduced Archive Size
If all simulation data is compressed only a fraction of the storage is required. Storage and backup capacities can hold more simulation results. Hence, investments in the growth of storage and archive infrastructures can be avoided.

Shorter Data Transfer Times
Transferring result data across computer networks can be very time consuming. Transmission speeds are limited by the available network bandwidth. Since compressed simulation results require significantly less storage they can be transferred in a fraction of the time required for transferring uncompressed results.

Quicker Data Loading
Reading data into post-processors can be a time consuming task as well. If data storage is provided on file servers, compressed data can be read directly into post processors significantly quicker due to the faster data transfer. In some cases load times can even be improved when reading from a local hard drive.

While providing these benefits FEMZIP is made to fit into the workflow used by engineers. It is designed to be integrated into batch processes to enable automated compression immediately after the simulation process. This way the engineer can benefit from data compression without the requirement of manually operating FEMZIP. Furthermore, on-the-fly decompression functionality of FEMZIP is integrated into common post-processing tools to make direct access to the content of compressed files possible. Hence, it is often not necessary to retrieve the original data formats with the stand-­alone decompression tool FEMUNZIP to view the compressed results.
