3D - Subaerial and Submarine solid slides

 

The two-dimensional domain [-2, 6] x [-1.85, 1.85] is discretized with Ax = 0.02 Tit and the number of layers was set up to 3. Similar results were observed if more layers are considered. The final time is 4 s, CFL number was set to 0.9 and g =. 9.81. The same boundary conditions as in the previous case were imposed. In order to capture turbulent processes, as in benchmark 1, the complete Navier-Stokes viscous stress tensor is used with the same subgrid model and coefficients. Figures 6 and 7 show the numerical results obtained for the subaerial test case, first presenting the comparison for the wave gauges (Fig. 6) and the for the runup gauges (Fig. 7) . The same comparison can be found in Figures 8 and 9 for the submerged test case.
