Flac3D to TOUGH2 mesh translator
The mesh translator from Flac3D files to TOUGH2 files can be found as a
function script “FLAC2TOUGH.m”. The use of this function is also straight-
forward, and does not require input. All you need are informations (files)
from Flac3D. Here the commands to extract such information that can be
saved as .txt files:
• list zone
(to be saved on file zone.txt)
• list zone gp
(to be saved on file zone gp.txt)
• list zone join
(to be saved on file zone join.txt)
• list gp pos
(to be saved on file gp pos.txt)
save all these files in the same folder where you run “FLAC2TOUGH” (i.e.
where you want “MESH” and “INCON” file to be created). As described
above, the script need to be installed by changing the MATLAB path. After
including the files in your selected folder in the path, simply run it as:
>>FLAC2TOUGH()
The script also include a function (called “create INCON”) to produce
the TOUGH2 “INCON” file. However the script will only produce the initial
condition with a linear gradient (9800 Pa/m and 25
◦
/km). The call is made
in the FLAC2TOUGH script by:
>>FLAC2TOUGH(ID,xyz_zones,0)
while ID and xyz zones are internal variable in the scope of the script and
should not be changed, the number 0 can be changed according to the “depth
of the zero” of your mesh. For example in te case of the example for the 2D
irregular mesh, the number should be set to 1500, since the mesh depth was
-1000 to 1000, but the mesh was supposed to simulate a domain ranging
from -500 to -2500 m, hence the depth of the zero would 1500 (see also
“examples/FLAC2TOUGH”).
Note also that the INCON was meant for ECO2N module. If you need
a different format then modify the function “create INCON” according to
your needs.
