This library computes FFTs in one or more dimensions. It is extremely fast. This package contains the statically linked library and the header files.

The Advanced Simulation Library (ASL) is a free and open source hardware accelerated multiphysics simulation platform (and an extensible general purpose tool for solving Partial Differential Equations).

Its computational engine is written in OpenCL and utilizes matrix-free solution techniques which enable extraordinarily high performance, memory efficiency and deployability on a variety of massively parallel architectures, ranging from inexpensive FPGAs, DSPs and GPUs up to heterogeneous clusters and supercomputers. The engine is hidden entirely behind simple C++ classes, so that no OpenCL knowledge is required from application programmers. Mesh-free, immersed boundary approach allows one to move from CAD directly to simulation drastically reducing pre-processing efforts and amount of potential errors.

ASL can be used to model various coupled physical and chemical phenomena and employed in a multitude of fields: computational fluid dynamics, virtual sensing, industrial process data validation and reconciliation, image-guided surgery, computer-aided engineering, design space exploration, crystallography, etc...

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.

dmsh: "The worst mesh generator you'll ever use."

Inspired by distmesh, dmsh is slow, requires a lot of memory, and isn't terribly robust either.

On the plus side, it's got a usable interface, is pure Python (and hence easily installable on any system), and if it works, it produces pretty high-quality meshes.

Combined with optimesh, dmsh produces the highest-quality 2D meshes in the west.

Example capabilities:

• Primitives
• circle, rectangle, polygon
• halfspace
• Combinations
• difference
• nonconstant edge length
• union
• intersection
• Transformations
• rotation, translation, scaling
• Local refinement

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.

The FEniCS Form Compiler FFC provides state-of-the-art automatic and efficient evaluation of general multilinear forms (variational formulations) for FEniCS. FFC functions as the form evaluation system for DOLFIN but can also be used to compile forms for other systems.

FFC works as a compiler for multilinear forms by generating code (C or C++) for the evaluation of a multilinear form given in mathematical notation. This new approach to form evaluation makes it possible to combine generality with efficiency; the form can be given in mathematical notation and the generated code is as efficient as hand-optimized code.

This package installs the next-generation FFC-X library for Python 3.

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.

Pythonic wrapper around FFTW, the speedy FFT library. The ultimate aim is to present a unified interface for all the possible transforms that FFTW can perform.

Both the complex DFT and the real DFT are supported, as well as arbitrary axes of abitrary shaped and strided arrays, which makes it almost feature equivalent to standard and real FFT functions of numpy.fft (indeed, it supports the clongdouble dtype which numpy.fft does not).

pyFFTW is BSD-licensed and should not be confused with python-fftw, a GPL-licensed python module with the same aim of providing python bindings to FFTW3. Or python3-gpyfft, which provides bindings to the OpenCL FFT library clFFT.

This package provides the Python 3 bindings.

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.

This package provides Python bindings to the NFFT library, useful for performing Fourier transforms on non-uniformly sampled data with efficient speed. The bindings were generated using Cython and abstract the creation and execution of NFFT plans out using classes.

opm-grid provides implementations of grids for reservoir simulation, corner point or more general pillar grids, following the DUNE grid interface: CpGrid, a parallel corner point grid, and PolyhedralGrid a more general serial grid implementation of an unstructured, legacy, grid.

A standard grid type in the petroleum industry, corner-point grids fills the domain with a relatively low number of cells while still providing sufficient flexibility to model faults, fractures and erosion. The grid format was originally designed with an eye towards geological modeling rather than numerical simulation, but is still suitable for e.g. low order finite volume discretizations.

This package provides the development files for the grid implementations, i.e. the headers and shared library links.
