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.

The latest released version of Feel++ is 0.105 and the documentation will be only updated to fix issues. The current development version of Feel++ is 0.106 and the associated documentation may be updated anytime.
The Feel++ documentation introduce the Feel++ concepts, the process to build and run an application and the process to run a toolbox application. New user should begin with the User Manual.

4. Infrastructure

Feel++ is available on various supercomputing infrastructures.

Atlas

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

Alsacalcul

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++.

5. 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.
