Export to HDF5

Warning

This tool is under construction and will not function for all data types.

This tool exports FLO-2D files into an HDF5 file.

HDF5 Data Structure

The program HDFView can be used to view the HDF5 file structure. The HDF5 file contains groups of datasets that flopro.exe reads to run the FLO-2D model. The datasets are organized in a way that is simpler than the original FLO-2D files, but still contains all the necessary information.

The HDF5 file will expand as more tables are added. The follwoing image shows the structure of an HDF5 with a grid and control data.

The tables are relatively simple as you can see in the coordinates table below. The coordinates table contains the x and y coordinates of the grid nodes.

HDFView can be downloaded from the HDF Group website.

See the Technical Reference Manual Appendix C for more details on the HDF5 file structure.

Note

The HDF5 file format is a binary format, so it cannot be opened in a text editor. It must be opened with a program that can read HDF5 files, such as HDFView.
