One of the main and responsible stages creating an apparatus for numerical analysis structures using finite element method is its implementation in form a set programs. The principles complex construction should take into account modern requirements strength calculation software complexes. Among them, first all, automation computing process, rational use resources operating external memory stor...

The objective of this work is to innovatively apply the boundary element method (BEM) as a general modeling strategy deal with complicated reservoir problems, especially those related heterogeneity and fracture systems, which are common challenges encountered in practice engineering. transient flow behaviors reservoirs containing multi-scale heterogeneities enclosed by arbitrarily shaped bounda...

The electromagnetic force between two misaligned coils (coils with parallel axes) with uniform current density distribution and rectangular cross section based on the derived semi-analytical expressions was presented. Using the semi-analytical expressions for magnetic force between filamentary misalignment circular coils we calculate the propulsive and the transverse magnetic force. In order to...

In this article an analytical technique, namely the homotopy analysis method (HAM), is applied to solve the momentum and energy equations in the case of a two-dimensional incompressible flow passing over a wedge. The trail and error method and Padé approximation strategies have been used to obtain the constant coefficients in the approximated solution. The effects of the polynomial terms of HAM...

A semi-analytical iterative method as one of the newest analytical methods is used for the elastic analysis of thick-walled spherical pressure vessels made of functionally graded materials subjected to internal pressure. This method is accurate, fast and has a reasonable order of convergence. It is assumed that material properties except Poisson’s ratio are graded through the thickness directio...
