HDF5 for CAE data exchange in Fibersim

HDF5 is a data model, library, and file format for storing and managing data. It supports an unlimited variety of datatypes, and is designed for flexible and efficient I/O and for high volume and complex data. HDF5 is portable and is extensible, allowing applications to evolve in their use of HDF5. Siemens has taken the initiative in adopting it to create a standard for exchanging composite CAE data, and now works with all the major CAE companies that use this format, such as ANSA. For more information on the format, please go here:

Using the HDF5 format for conveying composite data, Fibersim is able to export/import complete laminate definitions, including true fiber orientations, to/from CAE systems. Depending on the CAE application Fibersim is interfacing with, a variety of different composite data can be exchanged. These data include material information and properties, individual ply data (ply names, shapes, specified fiber orientations, layup sequence/step info, etc.), nominal thicknesses of layup, calculated (analytical) thicknesses of layup due to material deformation, and of course, true fiber orientations as simulated by Fibersim.

A variety of HDF5 tools, including a free viewer that can be used to view and edit the data can be found here:
