Numerical evaluation of a symmetric potential function

We discuss the numerical evaluation of a symmetric potential function which arises naturally in applications. We present a method designed to accurately and efficiently compute this integral, and compare the performance of this method with two other popular techniques. This method requires considerably fewer function evaluations than all other techniques we tested, and is applicable to any inte...

Evaluation of a circular symmetric function on a 2d-mesh

How to compute the (2n+1)(2n+1)-matrix f(i 2 +j 2)] ?ni;jn fast, given a program to evaluate f (s)? Using simple symmetries the matrix can be constructed by evaluating f at only 12:5% of all points. However for practical sizes (2n+1 512) about 7:5{8:5% are suucient since there are many integer points (i; j) with the same i 2 + j 2. We analyse how many points have to be considered at minimum, de...

Numerical Solution of the Symmetric Water Impact of a Wedge Considering Dynamic Equations of Motion

In this research, numerical simulation of a symmetric impact of a 2-D wedge, considering dynamic equations in two-phase flow is taken into account. The two-phase flow around the wedge is solved based on finite volume method and volume of fluid (VOF) scheme. The dynamic mesh model is used to simulate dynamic motion of the wedge, thereby the effects of different dynamic meshes in both structured ...

A New Modification of Morse Potential Energy Function

Interaction of meso — tetrakis (p-sulphonato phenyl) porphyrin (hereafter abbreviated to TSPP)with Na+ has been examined using HF level of theory with 6-31G* basis set. Counterpoise (CP)correction has been used to show the extent of the basis set superposition error (BSSE) on thepotential energy curves. The numbers of Na+ have a significant effect on the calculated potentialenergy curve (includ...

Numerical evaluation of the Riemann Zeta-function

We expose techniques that permit to approximate the Riemann Zeta function in different context. The motivation does not restrict only to the numerical verification of the Riemann hypothesis (see Numerical computations about the zeros of the zeta function) : in [5] for example, Lagarias and Odlyzko obtained the best asymptotic known method to compute π(x), the number of primes less than x, thank...
