Geometry-driven topological defects in a polar system

This repository contains the code used to generate the results and figures in the manuscript Guruciaga, Ichikawa et al., "Boundary geometry controls a topological defect transition that determines lumen nucleation in embryonic development". The code implements simulations and analysis of geometry-driven topological defects, including data processing and visualisation routines. This fixed, reproducible version version corresponds to the exact state of the code used in the publication.
