The HDF5Table library is an open-source solution for the efficient handling; exchange and interpolating access of typical datasets in system simulation. The library consists of C-functions; python scripts and examples and can be used with different applications like Modelica or Simulink. Furthermore a comprehensive set of tools that allows the user to create; migrate; edit; compare and manage the datasets is available.

The application range covers data import from measurements or other simulations; integration of datasets in preprocessing routines; the usage of the datasets in the simulation and the post processing of simulation results. To eliminate a major source of errors after data exchange between simulation tools or different companies and to validate the datasets each dataset can have a physical unit and quantity attached to it. The table data can be easily accessed with different methods for inter- and extrapolation. To persist and exchange the data sets a subset of the HDF5 standard is used. With the HDF5 API the data access is fast for large files with many variables containing millions of values and the datasets can be opened in many other tools.
