Feel++ will be present in the Rencontres INRIA Industrie showroom at the AMIES stand. The demo will be about Blood Flow Simulation.We present simulations of blood flows in complex realistic geometries, e.g. the arterial network. These simulations rely on high performance computing and parallel computing in particular without which these simulations would not be feasible. Different flow configurations will be presented as well as different models involving for example the interaction between the arterial wall and the blood. These simulations are done using a free software called Feel++.In a second part we present the VivaBrain project whose objectives are to simulate angiographic data in MRI based on anatomical, dynamical and realistic models obtained from real data. |

CEMRACS'12 is about High Performance Computing. Feel++ will be present in no less than 3 projects: - ViBaBrain: blood flows in the brain
- HAMM: domain decomposition methods
- RB4FASTSIM: reduced basis for multiphysics methods
A more detailed description of the projects in french here

The Vivabrain project has been selected by the ANR MN call for project Feel++ will be central in this project as it will provide the computational framework for blood flows in the brain. The purpose of this project is to develop a multidisciplinary pipeline for the generation of virtual (i.e., simulated) angiographic images (more precisely, Magnetic Resonance Angiographies, MRA) of the human brain, associated to their anatomical (3D) and hemodynamic (3D+t) models (providing ground-truths).

Feel++ is now ported and works on the TGCC. Scalability results and applications are on the way.

Seems like the parallel framework works well, I got access to a 32 procs machine with 64 Go of RAM and run the laplacian example in the tutorial on these 32 procs. The slow part is the mesh generation otherwise it is all good. Hopefully we will get some scalability figures soon. In the mean time here is a screenshot attached. Feel++ hides the mpi details and the code remains exactly the same between the sequential and parallel version.
This computation was made on a machine provided by J.F. Mehaut (UJF/LIG). |

Documentation for Feel++ is available online at [http://code.google.com/p/feelpp/ Feel++ Google Code page]. It comes in three flavors: a PDF manual, a Doxygen reference manual and wiki pages. |

Maintenance release 0.91.3 has been released. The main changes involved support for clang 3.1 and icc 12.1 as well as support for mips and s390 architectures on Debian. |

I cannot maintain Feel++ trac [1] anymore. As you can see it is in pretty bad shape. Since the feelpp,org domain and in particular Feel++ website is using Google Apps I have decided to take the step forward and move the Wiki, Bug Tracking, Downloads, Sources(git) to the Google Code Project [2]. I have created the Feelpp project [3] which we used last monday for the next issues to solve and tasks [4] we discussed. There is already one wiki page on PETSc command line options [5] for Feel++ application and the 0.91 release is also available [6]. Regarding git, I am pushing my repository to the feelpp git repo whenever I do it for svn. svn remains of course the main central repository.
After playing with it a bit, I found google code to be quite simple to use, fast and feature complete. Also most of us have a google account, hence no creation of new accounts.
I hope you will like the tool. Comments are of course welcome.

A maintenance release has been uploaded for Feel++. It fixes compilation issue with boost1.49 and simplifies the installation process. This release has been also uploaded into Debian |

Finally after many months of development Feel++ has been released with many changes all over the place. Among them, parallel computations are now possible with Feel++ although the work is not finished. Check out the NEWS file. A 0.91.1 release will certainly follow as a maintenance release. The Debian package for Feel++ on Amd64 is also available in unstable. |
