HydroGeoSphere/Flow Solution

The following instructions affect the I/O for the flow solution.

Echo to output
Causes heads, saturations, concentrations and velocities for the subsurface domain to be written to the .lst file as well as to the binary output files.
 * &bull; &bull; &bull;

Flux output nodes

 * 1) new_noutfc Number of new output nodes desired. Read the following new_noutfc times:
 * (a) ioutfc(i) Flux output node number. These values should be entered one per line.

Listed nodes are flagged as flux output nodes, at which detailed fluid flux [L3 T−1] information for the subsurface domain is output at each timestep. Flux output is written to a file called prefixo.flu. For each timestep in the flow solution, one line per flux output node will be written to the file. Each line contains the node number, time, fluid flux and nodal coordinates. Such output can be imported into an editor (e.g. Microsoft Excel) and sorted by column to facilitate, for example, the creation of a plot of fluid flux versus time at a node.

For an example which uses flux output nodes, see verification problem in Section 4.5.1.

Flux output nodes from chosen
This instruction works in a similar way to Flux output nodes except that all currently chosen nodes are flagged as flux output nodes.
 * &bull; &bull; &bull;

Binary flux output nodes
This instruction works in a similar way to Flux output nodes and requires identical input. However, it creates a binary file called prefixo.flu_b.
 * &bull; &bull; &bull;

Binary flux output nodes from chosen
This instruction works in a similar way to Binary flux output nodes except that all currently chosen nodes are flagged as flux output nodes.
 * &bull; &bull; &bull;

Output saltwater head
By default, when running density-dependent flow problems, the equivalent freshwater head is written to the head file (e.g. f_cdo.head.001). This instruction causes salt water heads to be written instead.
