Improvement of Absorbing Boundary Conditions for Non-Hydrostatic Wave-Flow Model SWASH

Abstract:

The performance of absorbing boundary conditions in SWASH is examined. The method to determine the sponge layer region in each processor when calculating with multiple processors is improved. An exponential decay function is employed to the momentum equations in the sponge layer region. The numerical tests show that the proposed damping coefficients work efficiently on reducing the wave energy of reflective waves in the sponge layer.
