HydroGeoSphere/Surface Flow Hydrographs

The following instructions affect the I/O for the surface flow solution:

Set hydrograph nodes

 * 1) label_hyd Descriptive name for the hydrograph up to 80 characters.

Chosen nodes are flagged as hydrograph nodes, at which detailed total fluid flux [L3 T−1] information is output at each timestep. Output is written to a TECPLOT-formatted file called prefixo.hydrograph.hydrograph.dat. For each timestep in the flow solution, one line will be written to the file. Each line contains the time, surface domain flux, porous media flux and total flux.
