A stabilized finite element method for advection-diffusion equations on surfaces
For researchers using finite element methods for surface PDEs, this provides a stabilization technique to handle advection-dominated transport, though it is an incremental extension of existing SUPG methods to surfaces.
The paper applies a stabilized finite element method (SUPG) to solve advection-diffusion equations on surfaces, addressing instability in advection-dominated regimes. Numerical experiments demonstrate improved stability and accuracy.
A recently developed Eulerian finite element method is applied to solve advection-diffusion equations posed on hypersurfaces. When transport processes on a surface dominate over diffusion, finite element methods tend to be unstable unless the mesh is sufficiently fine. The paper introduces a stabilized finite element formulation based on the SUPG technique. An error analysis of the method is given. Results of numerical experiments are presented that illustrate the performance of the stabilized method.
