Web5 de abr. de 2024 · The time marching method is the low storage five step fourth order Runge–Kutta scheme and Roe scheme is used as Riemann flux. In addition, to demonstrate the solving effect of low order calculation, the test with N = 2 is conducted, which uses 128 3 cells and contains 256 3 DOFs as well. WebThe fourth-order Runge-Kutta method requires four evaluations of the right-hand side per step h. This will be superior to the midpoint method if at least twice as large a step is possible. Generally speaking, high order does not always mean high accuracy. enabling others to act leadership
