Feel++ documentation

Welcome to Feel++ documentation! Feel++ is an Open-Source C++ library which allows to solve a large range of partial differential equations using Galerkin methods, e.g finite element method, spectral element method, discontinuous Galerkin methods or reduced basis methods. Feel++ enables parallel computing in a seamless way and allows to solve large scale systems up to tens of thousands of cores.

Table 1. Feel++ packages Docker (All platforms: Windows, Mac, Linux) and Debian/Ubuntu packages (Linux, Windows/WSL)

3. Feel++ Toolboxes

Feel++ toolboxes provides a environment for modeling and solving various kinds of scientific and engineering problems : Heat-transfer, CFD, CSM, FSI, Thermo-Electric, …​


4. Feel++ MOR

Feel++ comes with a Model Order Reduction framework.

Test cases are presented here.

5. Infrastructure

Feel++ is available on various supercomputing infrastructures.


Atlas is our local computing resource at Cemosis and IRMA laboratory. We open access to Atlas


Alsacalcul is the supercomputer at Université de Strasbourg. If you are a member of the university, you have access to Alsacalcul either through best effort or through dedicated calls. If you are a company, Cemosis is in charge of selling computing hours on Alsacalcul and providing associated services.

Finis Terrae 2

As one of the basic component of the MSO4SC E-INFRA H2020 project, Feel++ is available on Finis Terrae 2(FT2) from CESGA natively and via Singularity. If you are a CESGA/FT2 user, you have access to Feel++.

6. External Tools

6.1. Salome

Feel++ can use Salome and MeshGems.

Feel++ will soon be integrated with Salome.

Feel++ can use a license for MeshGems.

6.2. Slurm

How use Slurm for run Feel++ on supercomputing infrastructures.

7. Get Help

The Feel++ project is developed to help you easily do (i) modelisation simulation and optimisation and (ii) high performance computing. But your feedback is invaluable to make progress! We encourage you to ask questions and discuss any aspects of the project on the discussion list, on Twitter or in the chat room.
