FEniCS est une collection de logiciels libres pour la résolution automatique et rapide d’équations différentielles.

FEniCS possède une longue liste de fonctions, comprenant entre autres, la résolution automatique de problèmes variationnels, le contrôle automatique d’erreur, une bibliothèque complète d’éléments finis, une algèbre linéaire hautement performante.

FEniCS est organisée sous forme de collection de composants interopérables, comprenant l’environnement DOLFIN de résolution de problème, le compilateur de formes FFC, le « tabulateur » pour les éléments finis FIAT, le compilateur en temps réel Instant, l’interface de génération de code UFC, le langage de formes UFL et une variété de composants supplémentaires.

Il s’agit d’un métapaquet dépendant de tous les composants de FEniCS.

Il s’agit de la version historique de FEniCS. L’installation de la nouvelle génération, FEniCS-X (paquet fenicx), est à envisager.

La bibliothèque ASL (« Advanced Simulation Library » – bibliothèque de simulation évoluée) est une plateforme libre de simulation multiphysique accélérée matériellement et un outil généraliste extensible pour résoudre des équations aux dérivées partielles.

Son moteur de calcul est écrit en OpenCL et utilise des techniques de résolution sans matrices, ce qui permet des performances extraordinaires, une gestion de la mémoire efficace et déployabilité sur une variété d'architectures massivement parallèles, allant des FPGA, DSP et GPU peu onéreux jusqu'aux grappes et superordinateurs hétérogènes. Le moteur est entièrement caché derrière des classes C++ simples afin qu'aucune connaissance d'OpenCL ne soit requise par les programmeurs d'applications. L'approche sans maillage (« mesh-free ») et « immersed boundary » permet de passer de la CAO à la simulation en réduisant de façon drastique les efforts de prétraitement et le nombre d'erreurs potentielles.

ASL peut servir à modéliser divers phénomènes physiques et chimiques et être utilisé dans une multitude de domaines : mécanique des fluides numérique, détection virtuelle, validation et rapprochement de données de traitement industriel, chirurgie guidée par vidéo, ingénierie assistée par ordinateur, exploration d’alternatives de conception (DSE), cristallographie, etc.

Xray::Absorption supports access to X-ray absorption data. It is designed to be a transparent interface to absorption data from a variety of sources. Currently, the only sources of data are the 1969 McMaster tables, the 1999 Elam tables, the 1993 Henke tables, and the 1995 Chantler tables. The Brennan-Cowen implementation of the Cromer-Liberman tables is available as a drop-on-top addition to this package. More resources can be added easily.

Xray::SpaceGroup provides an object-oriented interface to a database of space group symmetries transcribed from volume A of the International Tables of Crystallography.

PyFAI is a Python library for azimuthal integration; it allows the conversion of diffraction images taken with 2D detectors like CCD cameras into X-Ray powder patterns that can be used by other software like Rietveld refinement tools (i.e. FullProf), phase analysis or texture analysis.

As PyFAI is a library, its main goal is to be integrated in other tools like PyMca, LiMa or EDNA. To perform online data analysis, the precise description of the experimental setup has to be known. This is the reason why PyFAI includes geometry optimization code working on "powder rings" of reference samples. Alternatively, PyFAI can also import geometries fitted with other tools like Fit2D.

PyFAI has been designed to work with any kind of detector with any geometry (transmission, reflection, off-axis, ...). It uses the Python library FabIO to read most images taken by diffractometer.

DOLFIN is the Python and C++ interface of the FEniCS project for the automated solution of differential equations, providing a consistent PSE (Problem Solving Environment) for solving ordinary and partial differential equations. Key features include a simple, consistent and intuitive object-oriented API; automatic and efficient evaluation of variational forms; automatic and efficient assembly of linear systems; and support for general families of finite elements.

This is the base package depending on specific dolfin builds. By default the version built against the preferred version of PETSc in /usr/lib/petsc is selected (with 32-bit indexing, but the alternative version (64-bit PETSc) can be selected by setting the environment variable PETSC_DIR.

This is the legacy version of DOLFIN, you may want to install the next-generation python3-dolfinx (DOLFIN-X) instead.

This python wrapper is designed to tightly integrate with PyOpenCL. It consists of a low-level Cython based wrapper with an interface similar to the underlying C library. On top of that it offers a high-level interface designed to work on data contained in instances of pyopencl.array.Array, a numpy work-alike array class for GPU computations. The high-level interface takes some inspiration from pyFFTW. For details of the high-level interface see fft.py.

pygalmesh makes it easy to create high-quality 3D volume and surface meshes.

CGAL offers two different approaches for mesh generation:

• Meshes defined implicitly by level sets of functions.
• Meshes defined by a set of bounding planes.

pygalmesh provides a front-end to the first approach, which has the following advantages and disadvantages:

• All boundary points are guaranteed to be in the level set within any specified residual. This results in smooth curved surfaces.
• Sharp intersections of subdomains (e.g., in unions or differences of sets) need to be specified manually (via feature edges, see below), which can be tedious.

On the other hand, the bounding-plane approach (realized by mshr), has the following properties:

• Smooth, curved domains are approximated by a set of bounding planes, resulting in more of less visible edges.
• Intersections of domains can be computed automatically, so domain unions etc. have sharp edges where they belong.

pygalmesh and mshr are therefore complementary.

pygalmesh also interfaces CGAL's 3D periodic mesh generation.

This package installs the pygalmesh module for Python 3.

It also provides the utility scripts pygalmesh-from-inr and pygalmesh-volume-from-surface for generating volume meshes from INR or surface meshes.
