Question

Initial guess for newton's method for pipe flow simulation

Answer 1

For implicitly discretized nonlinear evolution problems, a reduced model technique is developed for computing a better initial guess for the inexact Newton method. The computational effect of the chosen initial guess is :-) :-) :-)


Is there any criteria or a way to take a good initial guess for solving non-linear system of equations using Newton Method.Or one shoud try different guess randomly again and again until one get the required ...
