Efficient coupled deep neural networks for the time-dependent coupled Stokes-Darcy problems

作者:

Highlights:

• Our method compiles the interface conditions of the coupled PDEs into the networks properly.

• This method can be served as an efficient alternative to the complex coupled problems.

• We sampled randomly and only input spatial coordinates without being restricted by the nature of samples.

• Our method is meshfree and parallel which can solve multiple variables independently at the same time.

• We give the theory to guarantee the convergence of the loss function and the convergence of the neural networks to the exact solution.

• We present the numerical examples in both 2D and 3D cases.
