Courant number mean
WebThe new Shallow Water equation solution methodology (SWE-EM) uses an explicit solution scheme for solving the equations. While this method is more momentum conservative, it requires smaller computational time steps (i.e. in general, the time step must be selected to ensure the Courant number is less than 1.0). WebSep 4, 2024 · Subscriber. Hello, Courant number definition involves grid size, velocity scales and time step size. These three values are used to calculate what is popularly known as the CFL condition (please read …
