Test Results on Initial Value Methods for Non-Stiff Ordinary ...

WebbThe method is acausal, since the time dependence is calculated by a global minimization procedure acting on the time integrated problem. Recall that in standard WRM methods, initial value problems are transformed into a set of coupled ordinary, linear or non-linear, dif-ferential equations for the time-dependent expansion coefficients. WebbThe idea is to establish a set of auxiliary problems that can be solved to find initial conditions at one of the boundaries. Once the initial conditions are determined, the usual methods for solving initial value problems can be applied. The chasing method is, in effect, a shooting method that uses the linearity of the problem to good advantage. signification factice

WebbSince the initial value problem has a unique solution, this implies u(x,t) = u(−x,t). 2. Solve the Neumann problem for the wave equation on the half line. That is, ﬁnd the solution to (WE) when x>0 and the boundary condition ux(0,t) = 0 is imposed for WebbWhen using Newton’s method, each approximation after the initial guess is defined in terms of the previous approximation by using the same formula. In particular, by defining the function F(x) = x − [ f ( x) f ( x)], we can rewrite Equation 4.8 as xn = F(xn − 1).
