A minimizing movements approach for crystalline eikonal-curvature flows of spirals

Numerical Analysis 2025-04-08 v2 Numerical Analysis

Abstract

We propose an algorithm for evolving spiral curves on a planar domain by normal velocities depending on the so-called crystalline curvatures. The algorithm uses a minimizing movement approach and relies on a special level set method for embedding the spirals. We present numerical simulations and comparisons demonstrating the efficacy of the proposed numerical algorithm.
