摘要：Fractional-in-space Allen-Cahn equation containing a very strong nonlinearsource term and small perturbation shows metastability and a quartic double well potential.Using a finite volume unstructured triangular mesh method, the present paper solves the two-dimensional fractional-in-space Allem-Cahn equation with homogeneous Neumann boundarycondition on different irregular domains. The efficiency of the method is presented throughnumerical computation of the two-dimensional fractional-in-space Allen-Cahn equation ondifferent domains.
