WitrynaThe GFDM is applied for spatial discretization in a 2D computational domain, and the order of the Taylor series expansion is four or higher. Then, an overdetermined system of algebraic equations is yielded by applying the GFDM. To utilize the Newton-Raphson method to iterate the numerical solutions, the fictitious-nodes technique is used. Witrynar b a Compare with Equation 1: bis just the ‘next’ Newton-Raphson estimate of r.The new estimate bis obtained by drawing the tangent line at x= a,and then sliding to the x-axis along this tangent line.Now draw the tangent line at (b;f(b)) and ride the new tangent line to the x-axis to get a new estimatec.Repeat. We can use the geometric …
