FINITE ELEMENT METHOD - IIST
Direct Approach to Finite Element Method 2.1 Introduction The direct approach is related to the “direct stiffness method” of structural analysis and it is the easiest to understand when meeting FEM for the first time. The main advantage of this approach is that you can get a feel of basic techniques and the essential concept involved in

www.iist.ac.inThomas’ algorithm, also called TriDiagonal Matrix Algorithm (TDMA) is essentially the result of applying gaussian elimination to the tridiagonal system of equations. The ith equation in the system may be written as a iu i 1 + b iu i + c iu i+1 = d i (2) where a 1 =0 and c N =0. Looking at the system of equations, we see that ith unknown can be
