| Abstract: | We establish variational formulation and prove the existence and uniqueness of the three dimensional axisymmetric Stokes exterior problem in weighted spaces.Error estimates and convergence for P2-P0 elements with infinite element methods are also obtained.Numerical experiments are presented to verify the theoretical analysis. |
| Keywords: | Axisymmetric flow Stokes equation exterior problem infinite element method |
