What is Feel++ ?

Feel++ is a unified C++ implementation of Galerkin methods (finite and spectral element methods) in 1D, 2D and 3D to solve partial differential equations.

Feel++ is

1. a versatile mathematical kernel solving easily problems using different techniques thus allowing testing and comparing methods, e.g. cG versus dG.

2. a small and manageable library which nevertheless encompasses a wide range of numerical methods and techniques and in particular reduced order methods such as the reduced basis method.

3. a software that follows closely the mathematical abstractions associated with partial differential equations (PDE) and in particular the finite element mathematical framework and variational formulations.

4. a library that offers solving strategies that scales up to thousands and even tens of thousands of cores.

5. a library entirely in C++ allowing to create C++ complex and typically non-linear multi-physics applications currently in industry, physics and health-care.

Generating the website

Feel++ uses Antora to generate the website http://docs.feelpp.org.

❗	Prerequisites : npm, curl You can install these dependencies on Ubuntu/Debian OS by executing : sudo apt install npm curl

Once you have installed prerequisites, follow the next steps to generate a local preview of the website http://docs.feelpp.org.

git clone https://github.com/feelpp/book.feelpp.org.git # (1)
git clone https://github.com/feelpp/toolbox.git # (2)
cd book.feelpp.org # (3)
npm install # (4)
npm run dev # (5)
npm run serve # (6)

1. clone the source for the website

2. clone the source for toolbox cases doc

3. go the toplevel directory

4. install antora and some other dependencies

5. build a local preview of the website with Antora

6. start the node.js webserver serve, see the docs.
