relaxation parameter
hi friends,
When using PSOR (point successive over relaxation) method, we all know that relaxation parameter [say(w)] should be in between 0 and 2. And the optimum value of relaxation parameter (w) is derived from the equation w_optimum=(2-2(1-a)^0.5)/a and 'a'=f(ratio of deltax,deltay; and number of grid points). My question is what is the significance of this equation in finding out the relaxation parameter (w). I mean to say........what this equation actually doing by taking the parameters of grid. Any help in this regard is highly appreciated. Thanks in advance. rvndr |
