Meshing for the Finite Element Method

The standard nite element method doesn’t need to know element neighbors; however, there are many times when dealing with a mesh when this is necessary. For example, there’s a fast algorithm to nd a random point hidden in one of 1,000,000 elements that will take, on average, 500 trials, rather than 500,000,

Computational Geometry Lab: TETRAHEDRONS

Since a solid angle is associated with a vertex of the tetrahedron, we can use the notation SA.a to denote the solid angle associated with vertex a, for instance. A solid angle is the 3D analog of the plane angles we are familiar with from geometry. Unlike a triangle, however, the solid angles of a tetrahedron do not have to add up to a ...

Crank Nicolson Scheme for the Heat Equation

Crank Nicolson Scheme for the Heat Equation The goal of this section is to derive a 2-level scheme for the heat equation which has no stability requirement and is second order in both space and time. From our previous work we expect the scheme to be implicit. This scheme is called the Crank-Nicolson

Monte Carlo Method: Probability - People

The Monte Carlo Method is based on principles of probability and statistics. To begin our discussion, we will look at some basic ideas of probability; in particular, the idea of how the behavior of a system can be described by a curve called the probability density function, and how the properties of that curve can help us to understand a
