Scientific Computing Tools for Finite Element Methods

This package contains a collection of tools for scientific computing with a focus on finite element methods. The tools are written in Python and are intended to be used in conjunction with the dolfinx.

Many users that are transitioning from legacy FEniCS to FEniCSx may find the transition difficult due to the lack of some functionalities in FEniCSx. This package aims to provide some of the functionalities that are missing in FEniCSx. The package is still in its early stages and many functionalities are still missing.

Features

• Real-space implementation for usage in DOLFINx (>=v0.8.0)
• Save quadrature functions as point clouds
• Save any function that can tabulate dof coordinates as point clouds.
• Point sources for usage in DOLFINx (>=v0.8.0)
  • Point sources in vector spaces are only supported on v0.9.0, post DOLFINx PR 3429. For older versions, apply one point source in each sub space.

Installation

The package is partly written in C++ and relies on dolfinx. User are encouraged to install scifem in an environment where dolfinx is already installed. The package can be installed using pip:

python3 -m pip install scifem --no-build-isolation

or from git with

python3 -m pip install --no-build-isolation git+https://github.com/scientificcomputing/scifem.git
