FINITE ELEMENT METHOD - IIST
1.2. FINITE ELEMENT METHOD 5 1.2 Finite Element Method As mentioned earlier, the finite element method is a very versatile numerical technique and is a general purpose tool to solve any type of physical problems. It can be used to solve both field problems (governed by differential equations) and non-field problems.

Delta Function and Heaviside Function - IIST
www.iist.ac.inIf the delta function is acting at the origin, i.e., if a =0, the regularized delta function defined by (15) becomes δε(x)= 1 2ε 1+cos πx ε if −ε<x <ε, 0 otherwise. (17) Another example of regularized delta function is a sequence of bell-shaped pulses defined as δk(x−a)= 1 k √ 2π e− 1 2(x−a k) 2 (18) where k is a parameter.

Method of Characteristics - Home | IIST
www.iist.ac.inThe method of characteristics is a technique for solving hyperbolic partial differential equa-tions (PDE). Typically the method applies to first-order equations, although it is valid for any 3. hyperbolic-type PDEs. The method involves the determination of special curves, called char-

Tridiagonal Matrix Algorithm - Indian Institute of Space ...
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
