In this tutorial we learn how to install librheolef-dev on Debian 9. librheolef-dev is efficient Finite Element environment - development files

Introduction

In this tutorial we learn how to install librheolef-dev on Debian 9.

What is librheolef-dev

librheolef-dev 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 headers required for development.
