FEMZIP - CDH-AG

The FEMZIP products offers advanced numerical algorithms to efficiently compress result data of leading FEM solvers, including MSC.NASTRAN, NX-NASTRAN and ESI PAM-CRASH.

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.

FEMZIP is made to fit into the workflow used by engineers. In order to maximize the benefit of data compression, FEMZIP is designed to be integrated into batch processes. In this way, simulation results can be compressed automatically after they have been generated, reducing file sizes from the start.

Although the original data formats can be retrieved by a standalone decompression tool, this is often not necessary. The decompression functionality of FEMZIP is integrated in common post-processing tools and enables direct access to the content of compressed files.

FEMZIP does not alter existing workflows while providing the benefits of data compression.

Crash simulation is a standard CAE application in the automotive industry. The effort of improving car safety is accompanied by large numbers of simulations performed on a daily basis. As a result vast amounts of simulation data are continuously produced.

With FEMZIP for CRASH we offer a series of data compression solutions specially designed for commonly used crash-codes.

FEMZIP versions are available for PAM-CRASH, LS-DYNA and RADIOSS result files.

Typical crash result files can be reduced with FEMZIP by about a factor of 10. This reduction leads to considerably lower storage requirements, significantly shorter data transmission and quicker data loading. The latter can be experienced with a variety of post-processing tools that support the compressed data format of FEMZIP.

To improve the experience of working with FEMZIP compressed files, we have worked together with post-processor developers to enhance the integration of our decompression technology. Today, a large number of post-processors support our format, so that working with compressed files has become easier than ever before.

For noise, vibration, and harshness (NVH) analysis results are often calculated for a large number of modes. The emerging data of a single simulation usually comprises several GB of data. For collaborating engineers at different sites that have to exchange this data across telecommunication networks data transfer can become a bottleneck in their workflows.

Transfer times can be reduced significantly by employing FEMZIP. Instead of waiting for hours FEMZIP compressed NVH results can often be transferred in a matter of minutes. Consequently, a more fluent collaboration is possible.

FEMZIP-N supports MSC NASTRAN and RADIOSS results stored in the OP2 data format.
