We derive the explicit formulae for the spatial derivative and an explicit scheme by splitting the equation into a system of two parabolic PDEs. We prove the conditional convergence of the numerical scheme towards the continuous solution under certain assumptions. We obtain a second order approximation as it is clear from the numerical results. Finally, we provide several examples of its application over irregular domains in order to test the accuracy of the explicit scheme, as well as comparison with other numerical methods.eninfo:eu-repo/semantics/openAccess33 Ciencias Tecnológicas::3310 Tecnología industrialartículoGinzburg–Landau equationparabolic-parabolic systemsgeneralized finite difference method
