No module named fforces

[wenlingren]

When I work with toturial 3 using 'import fforces as ff'. there is a error 'No module named 'fforces''. I think I install sscha and cellconstructor properly. And I can run toturial 2 and 1 correctly. So where can I get the moudle 'fforces' and how can I install it.

Hi, the fforces is a toy model used in the tutorial is downloaded from the SSCHA repository; Basically:
git clone https://github.com/SSCHAcode/F3ToyModel

cd F3ToyModel

python setup.py install

Or copying from the installation part of the tutorial (probably you have an older version that didn't have this):

F3ToyModel installation

F3ToyModel is a force-field that can mimic the physics of ferroelectric transitions in FCC lattices. All preresquisites are met with the SSCHA installation.

The code for this force-field can be downloaded from the SSCHA github here <https://github.com/SSCHAcode/F3ToyModel>

Now enter the F3ToyModel directory and install with:

              python setup.py install
