Read/write functions for Telemac hydrodynamic model files (both Selafin and Leonard formats)

This set of m-files enables you to read, write and manipulate results files from the Telemac2D and 3D hydrodynamic modelling system of EDF/Sogreah. Both the triangular finite element grid (Selafin format) and square grid (Leonard format) are supported.

Usage examples have been included to help understand how to use the low level read and write functions so that you can incorporate them into your own Matlab code.

To get started, run the 'teldemo.m' script. This first calls 'telmean.m' which performs a time average on all the variables in the example hydrodynamic results file of the Mersey estuary (UK) and saves the answer to a new Selafin file. It then plots the mean water depth from the newly created file using 'telplot.m' (as shown in the screenshot).

I would like to acknowledge Dr Jon French of the Coastal and Estuarine Research Unit (University College London) for providing code that inspired these routines.
