Python module to replace variables and generate a full factorial design.
Considering a folder called 'skeletonFolder' containing the 'base_case.txt' file.
base_case.txt:
mass = __MASS__
velocity_x = __VELOCITY_X__
velocity_y = _VELOCITY_Y__
force_x = __FORCE_X__
You want to create new cases based on this layout, replacing the mass value by a constant, the velocity_x and velocity_y by a list, and force_x by a list dependent on velocity_x. You proceed with the following implementation:
example.py:
import supplant
sim = supplant.Configuration('skeletonFolder')
sim.add_constant('__MASS__', 1)
sim.add_variable('__VELOCITY_X__', [0.2, 0.4])
sim.add_variable('__VELOCITY_Y__', [-0.1, -0.5])
sim.add_dependent('__FORCE_X__', [200, 400], '__VELOCITY_X__')
sim.write_configurations()The final output will be 4 new cases (case_0 to case_3) containing the desired values.
