TWO-DIMENSIONAL ISOPARAMETRIC ELEMENT USING NEW DISCRETIZATION METHOD

An Enhanced Finite Element method for Two Dimensional Linear Viscoelasticity using Complex Fourier Elements

In this paper, the finite element analysis of two-dimensional linear viscoelastic problems is performed using quadrilateral complex Fourier elements and, the results are compared with those obtained by quadrilateral classic Lagrange elements. Complex Fourier shape functions contain a shape parameter which is a constant unknown parameter adopted to enhance approximation’s accuracy. Since the iso...

A two-dimensional resistance simulator using the boundary element method

A new resistance simulator for extraction of the parasitic parameters from VLSI layout is presented. The calculation of resistor network is based on the boundary element method (BEM). The computational results indicate that the BEM has an advantage over the finite difference method (FDM) and the finite element method (FEM). Since only discretized equations on the boundary of solved domain need ...

Application of the Boundary Element Method to two Dimensional Dynamic Problems of Saturated Porous Media

Application of Boundera Element Method (Bem) to Two-Dimensional Poisson's Eqation

BEM can be used to solve Poisson's equation if the right hand side of the equation  is constant because it can easily be transformed to an equivalent Laplace equation. However, if the right hand side is not constant, then such a treatment is impossible and part of the equation can not be transformed over the boundary, hence, the whole domain has to be discretized. Although this takes away impor...
