Abstract

In this paper, attention is focused on the study of the secant and Newton methods for solving nonlinear equations of air pressure distribution arising in finite element simulation of grain bin aeration problems. Element secant and tangential stiffness matrices for 2-D, 3-D and axisymmetric problems are deduced. The numerical examples show that the Newton method possesses the property of asymptotic rate of quadratic convergence, which can largely improve the computational efficiency of the finite element method. In addition, such issues as stream function arid isotraverse time line determinations are also discussed.
