How To Install rheolef on Debian 9
Introduction
In this tutorial we learn how to install rheolef on Debian 9.
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;
- Poisson problems in d=1,2 and 3 dimension with high order Lagrange elements, up to fifth order;
- linear elasticity, including incompressible and nearly incompressible elasticity;
- Stokes problems in d=2 or 3 dimension, with P2-P1 or P1 bubble-P1 elements;
- characteristic method for convection-diffusion, time-dependent problems and Navier-Stokes equations;
- nonlinear problems with either fixed-point algorithms or a provided generic damped Newton solver;
- 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 MayaVi, Paraview, and gnuplot.
There are three methods to install rheolef on Debian 9. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install rheolef Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get update
After updating apt database, We can install rheolef using apt-get by running the following command:
sudo apt-get -y install rheolef
Install rheolef Using apt
Update apt database with apt using the following command.
sudo apt update
After updating apt database, We can install rheolef using apt by running the following command:
sudo apt -y install rheolef
Install rheolef Using aptitude
If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Debian. Update apt database with aptitude using the following command.
sudo aptitude update
After updating apt database, We can install rheolef using aptitude by running the following command:
sudo aptitude -y install rheolef
