Witryna15 wrz 2015 · is to use implicit time marching. F urthermore, in many applications the conv ection terms. are often nonlinear, hence it would be d esirable to treat them explicitly while using implicit. Witrynadiffusion. Implicit time-marching methods which, like the ones presented in this paper, can relax or altogether eliminate such numerical stability constraints, often do so at the expense of high computing costs. Indeed, a typical implicit step requires the inver-sion of a large generally nonlinear system of equations which, in

In a most visible fashion this can be observed for collocation methods. The intermediate values of the method step can there be encoded in a polynomial p ( s) that (conceptually) approximates x ( t n + s h), with p ( 0) = x n. sierra wallace
