It utilizes an explicit finite volume formulation that captures the complex behaviors of models that consist of several stages, show large displacements and strains, exhibit non-linear material behavior, or are unstable (including cases of yield/failure over large areas, or total collapse). Go to extrusion pan of FLAC3D and click on the 'extrusion view' button. Such analyses include engineering design, factor of safety prediction, research and testing, and back-analysis of failure.

Reading TOUGH input and output files can be done using toughio. # Interpolate my_pp and my_temp from SAVE file
Flac3d from update#
To update a zone pore pressure and temperature, I don't remember if there is a zone array for these properties, but you can loop over each zone and update the parameters as follow: import itasca as it For instance, you can call an external program in Python as follow: import subprocess ¾reading the FLAC3D outputs from external files ¾creating standardized output files (to be read by FLAC3D) Develop T+H routines of models relating changes in the hydraulic properties of the porous medium to changes in stress and strain (inputs provided by the FLAC3D simulation). Loop back to step 1 until end of simulation.įLAC3D has a Python interface which should make this a bit easier to implement compared to using FISH.

The focus of this tutorial is to provide you with a basic famil. However, the TOUGHFLAC implementation is more optimized as it does not require to read and write TOUGH input/output files at each time step.Īssuming that you have already setup your problem for TOUGH and FLAC3D independently, a quick algorithm would look like as below:ġ. This tutorial steps through the actions necessary to quickly create and solve a FLAC3D model. It's even more complicated with TOUGH3 since you should now also consider that arrays are distributed in parallel. I am suggesting it since the current implementation of TOUGHFLAC (TOUGH calling FLAC) alters TOUGH source code a lot which requires a really good knowledge of the Fortran language. And the different numerical calculation methods also influence the safety factor of strength reduction method. However, it is short of unified instability evaluation standard at present. Floriane Youzan I didn't try the FLACTOUGH (FLAC calling TOUGH) implementation myself. Strength reduction method is widely used in the slope stability analysis.
