## Modules
The LMGC90, version 2017.rc1 is available on Salomon via module LMGC90:
## Modules
```sh
$ ml LMGC90
The LMGC90, version 2017.rc1 is available on Salomon via module LMGC90:
```
The module sets up environment variables and loads some other modules, required for running LMGC90 python scripts. This particular command loads the default module, which is LMGC90/2017.rc1-GCC-6.3.0-2.27, and modules: GCCcore/6.3.0, binutils/2.27-GCCcore-6.3.0, GCC/6.3.0-2.27, bzip2/1.0.6, zlib/1.2.8, ncurses/6.0, libreadline/6.3, Tcl/8.6.3, SQLite/3.8.8.1, Python/2.7.9
```sh
$ ml LMGC90
## Running generic example
```
LMGC90 software main API is a Python module. It comes with a pre-processor written in Python. There are several examples that You can copy from the *examples* directory which is in */apps/all/LMGC90/2017.rc1-GCC-6.3.0-2.27* folder. Follow the next steps to run one of them.

First choose an example and open a terminal in the directory of the copied example.
## Running generic example
### Generation
To have more information on the pre-processor open in a web navigator the file [docs/pre_lmgc/index.html][pre_lmgc].

To run an example, if there is no *DATBOX* directory or it is empty, run the Python generation script which is most time called *gen_sample.py* with the command:
First choose an example and open a terminal in the directory of the copied example.
```sh
$ python gen_sample.py
### Generation
```
You should now have a *DATBOX* directory containing all needed *.DAT* and *.INI* files.
To have more information on the pre-processor open in a web navigator the file [docs/pre_lmgc/index.html][pre_lmgc].
### Computation
To run an example, if there is no *DATBOX* directory or it is empty, run the Python generation script which is mostly called *gen_sample.py* with the command:
Now run the command script usually called *command.py*:
```sh
```sh
$ python command.py
$ python gen_sample.py
```
```
To get more information on the structure on command scripts read the documentation opening the file [docs/chipy/index.html][chipy] in a web browser.
Once the computation is done, you should have the directory *OUTBOX* containing ASCII output files, and a *DISPLAY* directory with output file readable by paraview.
You should now have a *DATBOX* directory containing all needed *.DAT* and *.INI* files.
### Postprocessing and Visualization
### Computation
The ASCII files in *POSTPRO* directory result from the commands in the *DATBOX/POSTPRO.DAT* file. To have more information on how to use this features read the documents [manuals/LMGC90_Postpro.pdf][LMGC90_Postpro.pdf].
The files inside the *DISPLAY* directory can be visualize with paraview. It is advised to read the *.pvd* files which ensure time consistency. The different output files are:
Now run the command script usually called *command.py*:
- tacts: contactors of rigid objects
- rigids: center of mass of rigid objects
```sh
- inter: interactions
$ python command.py
- mecafe: mechanical mesh
```
- therfe: thermal mesh
- porofe: porous mechanical mesh
To get more information on the structure on command scripts read the documentation opening the file [docs/chipy/index.html][chipy] in a web browser.
- multife: multi-phasic fluid in porous media mesh
