Dataset (codes and figures) for "Field‐controlled interfacial transport and pinning in an active spin system"

Dataset (codes and figures) for Field‐controlled interfacial transport and pinning in an active spin system, Phys. Rev. E 114, 014108 (2026). A preprint is available on arXiv. CODES: For each considered field (homogeneous unidirectional, bidirectional and random orientational fields), a C++ code to compute the numerical simulations of the microscopic model and a C++ code to compute the numerical solutions of the hydrodynamic equations are available in this repository.Compile: g++ filename.cpp -fopenmp -lgsl -lgslcblas -lm -O3 -s -o filename.out.Run: ./filename.out -parameter=value.List of parameters for the numerical simulations: beta, h, D, epsilon, rho0, LX, LY, init, tmax, ran, threads (details as comments in the code).List of parameters for the hydrodynamic solutions: beta, epsilon, rho0, h, LX, LY, init, dt, tmax, dx, ran, threads (details as comments in the code).
