MT3D OUTPUT

Standard Output File (unit 16)

Echos input, prints concentrations for each species, other information such as model-calculated parameters and mass budgets, at user-specified times and at the end of each stress period.

Unformatted Concentration File (start at unit 201)

One of these is created for each species, (the default name is MT3Dnnn.UCN where nnn is the species index number) and contains concentrations at user-selected times in binary for post-processing and restarting.

Observation File (start at 401)

One of these is created for each species (the default name is MT3Dnnn.OBS where nnn is the species index number) and contains concentrations versus total elapsed time at user-specified observation points for every transport step or at each user-specified interval.

Mass Budget Summary File (start at 601)

One of these is created for each species (the default name MT3Dnnn.MAS where nnn is the species index number)and contains a one-line summary of mass budgets for every transport step or at each user-specified interval.

Model Grid Configuration File (default name MT3D.CNF, unit 17)

This contains model spatial discretization information used by post-processors.
