There is currently no graphical postprocessor for HBGC123D. However, beginning with release version 1.1, we offer a non-graphical postprocessor in order to prepare the simulation data for third-party software like Excel, Gnuplot, Surfer, and GMS.
Overview
Usage instructions
Installation instructions
The postprocessing of HBGC123D simulation data is performed in two steps:
0 - Quit PostHBGC
This option exits the program. If you started it from the Windows Explorer,
its window will disappear. If you started it from a Windows command prompt
or a UNIX shell, you return to command mode.
1 - Display short help text
A short help text with an overview of the available options is displayed.
2 - Read HBGC123D binary output file
You may read as many HBGC123D output files as you like. The only restriction
comes from the available computer memory. If you run out of memory, quit
PostHBGC and restart it to process the remaining output files.
The HBGC123D superfiles for the samples have been set up to use ".binout" as
the extension for the binary output file. However, there is no restriction on
the name of this file.
If you try to read a file that is not a binary output file of HBGC123D
(version 1.1), an error message is displayed and the program returns to the
main menu.
3 - Select an output file
If you have read more than one file,
you can select one of them as the currently
active file. Otherwise you will be prompted in
most options to select one
of the available output files. The difference between these two choices is
that the selection made from the main menu will be in effect for all options,
while the selection of one file within an option will not effect other options.
4 - Display general information about output files
PostHBGC will display general information (simulation title,
number of nodes, elements,
components, and species, and names of components and species).
5 - Display time step data
PostHBGC will display the available output time steps.
6 - Display geometry data of nodes
PostHBGC will display the geometry data of nodes (coordinates and
connected elements).
7 - Display geometry data of elements
PostHBGC will display the geometry data of elements (node vertices and
material types).
8 - Display hydrology data of nodes (velocity, density)
PostHBGC will display hydrology data of nodes (velocities and densities).
9 - Display hydrology data of elements (water content)
PostHBGC will display hydrology data of elements (water contents).
10 - Display all concentration data for individual nodes
PostHBGC will display all concentrations (components and species, also
temperature if available) for one node.
11 - Define a list of nodes for histories (option 12)
or a profile (option 13)
This option allows you to enter a list of nodes (in arbitrary order) that
can be used for the creation of
history files and
profile files.
The order of input is irrelevant for history files since one file will be
created for each node you have selected. However, the order of input will
be maintained for the profile files. PostHBGC does not verify whether the
order of nodes represents a geometric profile across the model domain.
12 - Create history files for Excel, Gnuplot, etc.
PostHBGC allows the output of history curves (concentration-time curves) for
all simulations. If you run PostHBGC on Windows, the output will be a
comma-separated file (CSV). If you run it on UNIX, the data columns are
separated by spaces (Gnuplot compatible).
You can either use a list of nodes that was created by a call to
option 11 or define the list in this
option. You can also save the new or extended list of nodes in a file.
13 - Create profile files for Excel, Gnuplot, etc.
Profiles (concentrations in space at fixed times) can also be created from
all simulations. For one-dimensional simulations, a profile is automatically
defined as the sequence of concentrations along nodes, from 1 to the highest
node number. For 2D and 3D simulations, however, the user needs to define
the profile. (PostHBGC does not verify whether or not the entered data
represent a profile in a geometric sense.)
For instance, suppose you have a
regularly numbered mesh in two dimensions with 20 nodes in x-direction and
50 nodes in z-direction, with the inner loop of node numbering
being in z-direction.
You may enter "26" as the first node, "976" as the last node, and "50" as
the increment, if you want to create a profile in x-direction along the
medium value of the z-direction.
You can also use a list of nodes that was created by a call to
option 11.
14 - Create input data files for Surfer (2D only!)
For 2D simulations you can create Surfer compatible input data. (This option
is also available for the UNIX version of PostHBGC.)
15 - Create input data files for GMS (2D and 3D)
For 2D and 3D simulations you can create GMS (Groundwater Modeling System)
input data (super file, mesh file, concentration data files for all
components and species separately, and a velocity file).
16 - Find closest nodes to a given location
You can also find the closest
node to a location within the model domain. This is useful e.g. if you want to
compare data for a well with your simulation data.
Option:
Whenever you return to the main menu, enter the number of the option
you want to invoke on the keyboard, followed by ENTER.
If you entered invalid characters or a number that does not correspond
to an available option, an error message is issued and the program allows
you to enter an option number again.
