Nonconforming time discretization based on Robin transmission conditions for the Stokes–Darcy system

作者:

Highlights:

• The Stokes and Darcy system is formulated as a time-dependent interface problem.

• The decoupling algorithm is developed based on Robin–Robin transmission conditions.

• The Stokes and Darcy problems are solved independently and globally in time.

• Local time-stepping schemes with nonconforming time grids can be used.

• The use of nonconforming time grids significantly improves the efficiency.
