Print Frequency Dialog Box
The Print Frequency dialog box is used to specify
the simulation times at which PHAST will generate output. To
display the Print Frequency dialog box, select PHAST
Options|Print Frequency…
The main part of the dialog box is occupied by a table listing the
items that can be printed, the files to which they are printed, and the
frequency with which they are printed. The Add, Insert,
and Delete
buttons are used to add, insert, or delete columns in the table. The
Add button adds a new column at the end of the table. The Insert
button inserts a new column before the selected column. The
Delete button deletes the selected column. When a column is added
to the table, the values in the new column will be the same as in the
preceding column. When a column is inserted into the table, the
values in the new column will be the same as in the column before which
it was inserted.
To enter a frequency, the user selects one of the choices for units
from the drop down list of units for each type of output at each
time. One of the choices for units is "default". If that
choice is selected, the units on the “Title
and Units Dialog Box” (p.
65) will be used. If the units
are set to "end", the data will be
saved at the end of the simulation period and no numeric value can be
entered for time. If a numeric value is required, it is entered
in the edit box before the units.
At the bottom of the dialog box is the “Save final heads” check
box. If this check box is checked, heads will be saved to the
file *.head.dat at the end of the simulation. The file *.head.dat is an
ASCII file that can be used for initial head conditions in subsequent
simulations. Initial heads can be imported into GoPhast from the file
using the File|Import|Distributed
Data by Zone… menu
item (p. 29).
The items specified in each row of the table are as follows.
- Time represents the simulation time at which the
remaining items in the column take effect. No units are specified
for time. It is not required that a time match the times
specified in other parts of the model. All the specified times in
all parts of the model will be combined properly when preparing the
PHAST input file.
- Flow rates in boundary condition cells
determines the frequency with which flow rates in boundary conditions
cells are save to the *.O.bcf file. By default, they are not
saved.
- Components determines the frequency with which
total chemical element (component) data for each cell are written to
the *.O.comps file.
- Conductance determines the frequency with which
static fluid and transient solute dispersive conductances for each cell
face are written to the *.O.kd file.
- Flow balance determines the frequency with which
flow-balance information is written to the *.O.bal file.
- Force chemistry print determines the frequency
with which detailed chemical descriptions of the composition of the
solution and all reactants for each cell are written to the *.O.chem
file. Warning: this file could exceed file-size limits of the operating
system because a long description of the chemistry in each cell is
written for each selected time step. Writing this information may be
useful for debugging, for small problems, or if the Print_Chemistry
data set is used to limit the set of cells for which data are written.
Data written to the file *.O.chem also can be limited by the options of
the PRINT data block of the chemistry data file.
- HDF chemistry determines the frequency with
which chemistry data are written to the *.h5 file. Chemistry data to be
written to the file *.h5 are defined in the SELECTED_OUTPUT and
USER_PUNCH data blocks of the chemistry data file. The *.h5 file
is used by Model Viewer (Hsieh and Winston, 2002) when displaying data
from PHAST models.
- HDF heads determines the frequency with which
heads are written to the *.h5 file. The *.h5 file is used by
Model Viewer when displaying data from PHAST models.
- HDF velocities determines the frequency with
which X, Y, and Z velocities are written to the *.h5 file. The
*.h5 file is used by Model Viewer when displaying data from PHAST
models.
- Heads determines the frequency with which
potentiometric heads are written to the *.O.head file.
- Progress statistics determines the frequency
with which solver statistics, including solution-method information,
number of iterations, and maximum changes in head and component
concentrations (due to transport) are written to the *.log file and to
the screen.
- Velocities determines the frequency with which
interstitial velocities at cell boundaries and interpolated velocities
at nodes are written to the *.O.vel file.
- Wells determines the frequency with which
transient well information, including fluid and solute flow rates,
cumulative fluid and solute flow amounts, and solute concentrations,
are written to the *.O.wel file. Data are written in the order of the
well sequence numbers.
- XYZ chemistry determines the frequency with
which selected chemical data are written to the *.xyz.chem file. The
SELECTED_OUTPUT and USER_PUNCH data blocks of the chemistry data file
are used to select data that are written to the file prefix.xyz.chem.
Cells for which results are to be written can be restricted with the
Print_XYZ_Chemistry data set.
- XYZ components determines the frequency with
which component (chemical element) concentrations are written to the
*.xyz.comps file.
- XYZ heads determines the frequency with which
heads are written to the *.xyz.head file.
- XYZ velocities determines the frequency with
which interpolated velocities at cell nodes are written to the
*.xyz.vel file.
- XYZ wells determines the frequency with which a
time-series of concentrations for each well are written to the
*.xyz.wel.
- Boundary conditions determines whether heads,
component concentrations, fluxes, and other boundary-condition
information are written to the *.O.probdef file. The *.O.probdef
file can be used to document the boundary conditions in a way that is
easier for humans to read than are the model input files.
