Introduction

In this tutorial we learn how to install rheolef on Ubuntu.

What is `rheolef`

rheolef is:

Rheolef is a computer environment that serves as a convenient laboratory for computations in applied mathematics involving finite element-like methods. It provides a set of commands and C++ algorithms and containers.

Most basically, containers cover the classic graph data structure for sparse matrix formats and finite element meshes. At a higher level of abstraction, they can handle approximate finite element spaces, discrete fields. Flexible and powerful expressions are used to specify bilinear forms.

Current applications include:

massively distributed memory finite element environment, based on MPI;
elasticity, Stokes and Navier-Stokes problems in 2D and 3D;
complex fluids applications: viscoplasticity, viscoelasticity, wall slip;
nonlinear problems with fixed-point, Newton and continuation methods;
high order polynomials, mixed elements and discontinuous Galerkin methods;
auto-adaptive mesh approaches;
axisymmetric problems;
multi-regions and variable coefficient problems.

This package provides the rheolef commands. These support input and output in various file formats for mesh-generators and numerical data visualization systems such as paraview, and gnuplot.

There are three methods to install rheolef on Ubuntu. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
