# Simulating the interaction between a falling super-quadric object and a soap film

## TL;DR

This study uses 3D simulations to analyze how different shapes and orientations of a falling super-quadric object interact with a soap film, revealing deformation patterns and forces involved.

## Contribution

It introduces a detailed simulation framework for the interaction between complex-shaped objects and soap films, exploring shape, orientation, and force dynamics.

## Key findings

- Cubic particles experience the largest drag force in certain orientations.
- The most probable orientation of a cube falling through foam is identified.
- Deformation patterns depend on shape and initial orientation.

## Abstract

The interaction that occurs between a light solid object and a horizontal soap film of a bamboo foam contained in a cylindrical tube is simulated in 3D. We vary the shape of the falling object from a sphere to a cube by changing a single shape parameter as well as varying the initial orientation and position of the object. We investigate in detail how the soap film deforms in all these cases, and determine the network and pressure forces that a foam exerts on a falling object, due to surface tension and bubble pressure respectively. We show that a cubic particle in a particular orientation experiences the largest drag force, and that this orientation is also the most likely outcome of dropping a cube from an arbitrary orientation through a bamboo foam.
