The main output file of MOC3D is the listing file MOC3D.LST. MOC3D includes output
options to create separate ASCII or binary files for concentration, velocity and the location of
particles. Optionally the dispersion equation coefficients on cell faces can be written to the listing
file. The dispersion equation coefficient is a combination of dispersion coefficient D, porosity
n, thickness b and an appropriate grid dimension factor. For example, the dispersion equation
coefficient for the j+1/2, i, k face in the column direction is (n @b@D ) / )x.
xx j+1/2, i, k
The output from MOC3D are controlled by using the Output Control (MOC3D) dialog box
(Fig. 3.38). Most items in this dialog box are self-explanatory. The names of the separate ASCII
or binary output files are given in Table 3.6.
