Quadrature based optimal iterative methods
Sanjay K. Khattri, Ravi P. Agarwal
We present a simple yet powerful and applicable quadrature based scheme for constructing optimal iterative methods. According to the, still unproved, Kung-Traub conjecture an optim…
How to increase convergence order of Newton's method to ?
Sanjay Kumar Khattri
We present a simple yet powerful technique for forming iterative methods of various convergence orders. Methods of various convergence orders (four, six, eight and ten) are formed…
Grid Generation and Adaptation by Functionals
sanjay kumar khattri
Accuracy of a simulation is strongly depend on the grid quality. Here, quality means orthogonality at the boundaries and quasi-orthogonality within the critical regions, smoothness…
Multiblock Grid Generation for Simulations in Geological Formations
Sanjay Kumar Khattri
Simulating fluid flow in geological formations requires mesh generation, lithology mapping to the cells, and computing geometric properties such as normal vectors and volume of cel…
Computationally Efficient Technique for Nonlinear Poisson-Boltzmann Equation
Sanjay Kumar Khattri
Discretization of non-linear Poisson-Boltzmann Equation equations results in a system of non-linear equations with symmetric Jacobian. The Newton algorithm is the most useful tool…
Adaptive Quadrilateral Mesh in Curved Domains
Sanjay Kumar Khattri
Nonlinear elliptic system for generating adaptive quadrilateral meshes in curved domains is presented. Presented technique has been implemented in the C++ language. The included so…
