## Features addressed in this tutorial
|
|
|
|
|
|
* Python ONELAB model
|
|
|
|
|
|
## Additional information
|
|
|
|
|
|
Any Python script can become a native ONELAB client by importing the
|
|
|
`[onelab.py](https://gitlab.onelab.info/gmsh/gmsh/tree/master/contrib/onelab/python/onelab.py)`
|
|
|
module. This module comes pre-installed with Gmsh, in the same directory as the
|
|
|
Gmsh executable. When you open a ONELAB-enabled Python solver with Gmsh, Gmsh
|
|
|
automatically finds the onelab.py module. You can also install `onelab.py` in
|
|
|
any directory of your choosing; in this case don't forget to update your
|
|
|
`PYTHONPATH` environment variable.
