How To Install librheolef-dev on Ubuntu 20.04
Introduction
In this tutorial we learn how to install librheolef-dev
on Ubuntu 20.04.
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;
- 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 headers required for development.
