Appendix A.3 Model
These file are written by the modeling application. The fin (FEHM) or ama (Amanzi) file provides the internodal liquid flux values. The avs file provides Porosity, liquid saturation and liquid density used by the model application. See FEHM or Amanzi documentation for more on these files.
Note: The order of values in these files must be the same order as the node numbering in the Geometry files.
A.3.1 Flux fin or ama
The fin flux file is an FEHM restart file in ASCII format.
The file includes the number of mass flux values followed by mass flux value (kg/s) for each connection of each node, starting with node 1.
If the liquid fluxes are not found in the fin file, Walkabout will terminate.
Figure A3-1 shows an example for 20 nodes.

Figure A3-1 fin file with flux values
The ama flux file is written by Amanzi. The model velocity fields are calculated from the cell centers to the vertices in node order Vx, Vy, Vz.
The first line of the file is the number of nodes.
Figure A3-2 shows an example for 20 nodes.

A.3.2 Properties avs
Porosity, liquid saturation and liquid density are read from an ASCII avs file produced by the model application (the contour macro in FEHM). This uses an AVS file format for node attributes. The first line of the header indicates number of attributes followed by integer 1 indicating scalar value for each of the four attributes. The remainder of the header is a list of attribute names with optional dimension. The header is followed by columns of node number and values for the property data (attributes). Figure A3-3 shows an example for 20 nodes.
