内容摘要： The purpose of this talk is to present the numerical methods for the coupled Stokes and Darcy problem with solute transport. We present a weak formulation and then construct mixed finite element methods for the coupled flow problem using the nonconforming piecewise linear Crouzeix-Raviart element for the velocity and piecewise constant for pressure, usual mixed element methods, such as R-T or B-D-M element, can also be adapted using the samilar weak formulation. And we use classical piecewise linear finite element for concentration. Both same and different time step techniques are used in Stokes and Darcy regions. |
