# To reproduce the data needed for Figure 7 in associated original paper,
# execute this script in the Python console in OpenCOR. This can be done
# with the following commands at the prompt in the OpenCOR Python console:
#
# In [1]: cd path/to/folder_this_file_is_in
# In [2]: Fig2_sim.py

# Load the simulation file

# and pointers to the OpenCOR internal data representations
data = simulation.data()
# Set the experiments
