HPC Introduction: Difference between revisions

TUFLOW HPC is an explicit finitesolver for the full 2D Shallow Water Equations, including a sub-grid scale eddy viscosity model. The scheme is both volume solutionand momentum conserving, is 2nd order in space and 4th order in time, with adaptive or fixed timestepping. It is unconditionally stable. TUFLOW HPC's computational approach differs from TUFLOW Classic, which is ana 2nd order (space) implicit finite difference equationsolver. Both TUFLOW HPC and Classic solve the 2D Shallow Water Equations (including inertia and sub-grid scale turbulence or eddy viscosity terms) on the same uniform Cartesian grid configuration. Computationally each 2D cell includes 9 sub-grid points.<br>
