How To Install librheolef1 on Debian 9
Introduction
In this tutorial we learn how to install librheolef1 on Debian 9.
What is librheolef1
librheolef1 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 shared library.
