Chapter 1 Introduction
FreeFEM is an implementation of the Gfem language dedicated
to the finite element method. It provides you a way to solve Partial
Differential Equations (PDE) simply. Although you can solve quite complicated
problems can be solved also.
In this manual we are going to describe the FreeFEM package:
- How to use the language
- A quick presentation of how it is done
- A triangulation, T, is a set of triangles covering a domain
refered later as Ω
- Each vertex has a number iv, a region reference number
region, and a boundary reference number ib which is zero for
- An array-function is an array of values on the vertices of T. It
represents a piecewise linear continuous (or discontinuous if
precise is used) function on Ω.
- In an integrated environment Gfem has the notion of Project: files
shown on the desktop as documents with an icon like a triangulated
rectangle (on the Macintosh).
- A project contains a program, the last triangulation created and one
array function, namely the last function displayed.
