vedo - A python module for scientific analysis of 3D objects based on VTK and numpy

  •    Python

vedo is a lightweight and powerful python module for scientific analysis and visualization of 3d objects. Inspired by the vpython manifesto "3D programming for ordinary mortals", vedo makes it easy to work with 3D pointclouds, meshes and volumes, in just a few lines of code, even for less experienced programmers.

precice - A coupling library for partitioned multi-physics simulations, including, but not restricted to fluid-structure interaction and conjugate heat transfer simulations

  •    C++

preCICE stands for Precise Code Interaction Coupling Environment. Its main component is a library that can be used by simulation programs to be coupled together in a partitioned way, enabling multi-physics simulations, such as fluid-structure interaction. If you are new to preCICE, please have a look at our documentation and at precice.org. You may also prefer to get and install a binary package for the latest release (master branch).

fenics-adapter - preCICE-adapter for the open source computing platform FEniCS (see https://arxiv

  •    Python

preCICE-adapter for the open source computing platform FEniCS. Note: The adapter currently only supports 2D simulations in FEniCS. After cloning this repository and switching to the root directory (fenics-adapter), run pip3 install --user . from your shell.

shenfun - High performance computational platform in Python for the spectral Galerkin method

  •    Python

Shenfun is a high performance computing platform for solving partial differential equations (PDEs) by the spectral Galerkin method. The user interface to shenfun is very similar to FEniCS, but applications are limited to multidimensional tensor product grids, using either Cartesian or curvilinear grids (e.g., but not limited to, polar, cylindrical, spherical or parabolic). The code is parallelized with MPI through the mpi4py-fft package. Shenfun enables fast development of efficient and accurate PDE solvers (spectral order and accuracy), in the comfortable high-level Python language. The spectral accuracy is ensured by using high-order global orthogonal basis functions (Fourier, Legendre, Chebyshev, Laguerre, Hermite and Jacobi), as opposed to finite element codes that are using low-order local basis functions. Efficiency is ensured through vectorization (Numpy), parallelization (mpi4py) and by moving critical routines to Cython or Numba. Shenfun has been used to run turbulence simulations (Direct Numerical Simulations) on thousands of processors on high-performance supercomputers, see the spectralDNS repository.

dolfinx - Next generation FEniCS problem solving environment

  •    C++

DOLFINx is a new version of DOLFIN. It is being actively developed and features may come and go as development proceeds. DOLFINx is the computational environment of FEniCS and implements the FEniCS Problem Solving Environment in Python and C++.

ffcx - Next generation FEniCS Form Compiler

  •    Python

FFCx is a new version of the FEniCS Form Compiler. It is being actively developed and is compatible with DOLFINx. FFCx is a compiler for finite element variational forms. From a high-level description of the form in the Unified Form Language (UFL), it generates efficient low-level C code that can be used to assemble the corresponding discrete operator (tensor). In particular, a bilinear form may be assembled into a matrix and a linear form may be assembled into a vector. FFCx may be used either from the command line (by invoking the ffcx command) or as a Python module (import ffcx).

fiat - FIAT: FInite element Automatic Tabulator

  •    Python

The FInite element Automatic Tabulator FIAT supports generation of arbitrary order instances of the Lagrange elements on lines, triangles, and tetrahedra. It is also capable of generating arbitrary order instances of Jacobi-type quadrature rules on the same element shapes. Further, H(div) and H(curl) conforming finite element spaces such as the families of Raviart-Thomas, Brezzi-Douglas-Marini and Nedelec are supported on triangles and tetrahedra. Upcoming versions will also support Hermite and nonconforming elements. FIAT is part of the FEniCS Project.

ufl - UFL - Unified Form Language

  •    Python

The Unified Form Language (UFL) is a domain specific language for declaration of finite element discretizations of variational forms. More precisely, it defines a flexible interface for choosing finite element spaces and defining expressions for weak forms in a notation close to mathematical notation. Documentation can be viewed at https://fenics-ufl.readthedocs.org/.
