MOOSE Python Tools

The MOOSE code itself is written in C++, but everything around it that supports it is written in Python. Here we detail some of the tools/scripts developed in Python that are distributed with MOOSE. Click on each one for further information

MOOSE includes various python packages within the python directory. In order to use these packages the python directory must be made available to the interpreter, which is accomplished by setting the PYTHONPATH environment variable. The following can be set on the command line or inserted into your bash environment.

export PYTHONPATH=$PYTHONPATH:~/projects/moose/python
