报告摘要：Due to their remarkable characteristics, tubular geometries have been used in various theoretical and application scenarios. In this talk, we introduce efficient finite difference methods designed for computational problems on tubular geometries. First, we define a curvilinear coordinate system for tubular geometries. We then derive the Riemannian metrics and the corresponding expression for the Laplacian operator in these curvilinear coordinates. Subsequently, we propose finite difference schemes for a steady-state problem, Gray-Scott and Cahn-Hilliard models, accompanied by rigorous theoretical analysis. Numerical experiments demonstrate the efficiency and accuracy of the proposed methods.
