For noise vibration harshness (NVH) analysis results are often calculated for a large number of modes. The emerging data of a single simulation usually comprises several GBs 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 RASIOSS results stored in the OP2 data format.

Test results for Nastran OP2 file: Car model with 1428719 nodes. Solution Type 103, 51 modes.
Test results for Radioss OP2 file: Car model with 1026074 nodes. Solution Type 101, 29 modes.

While very efficient compression is obtained for standard sized models, even larger compression factors are possible for results with hundreds or thousands of modes. In some cases it is possible to reduce result files by a factor of 40.
