Simulating the interaction between a falling solid object and a soap film

Simulations were conducted in Surface Evolver, Version 2.70. See http://facstaff.susqu.edu/brakke/evolver/evolver.html, starting from the structure given in the file superquad_soapfilm_sim.fe. At each iteration, we dump information about the energy of the structure, the position and orientation of the super-quadric object, and the forces exerted on the object by the foam into the given data files. Information about the relevant parameters for each data file is given below. To generate the figures plotted in the paper, we analysed this data using bespoke Python programs and plotted the result using the matplotlib library and gnuplot, version 5.0 (http://www.gnuplot.info/). The snapshots from the simulations are generated directly from Surface Evolver.
