# peri3dController_shear.py
# script, that explains funcionality and input parameters of Peri3dController on the example of
# shear test with rotated periodic cell (that enables strain localization).
#   The simulation is run on rotated cell to enable localization and strain softening
# (you can also try simulation with different angles of rotation to pbtain different results.
