panta-rhei 0.7.2

Miscellaneous fenics/dolfin utilities that are used in various projects.

Panta Rhei

A collection of utilities for fluid flow modelling using FeNICS.

Note: This package was originally Pantarei, but was renamed to Panta Rhei in a hurry to avoid conflicts with a package of the same name on PyPI. For backwards compatibility, it is still imported as pantarei, but this will be changed in the future.

Dependencies

The package depends on FEniCS and SVMTK, which is not installed by default, since they are not available on PyPI. They are most easily installed using conda, by running the following commands:

conda create -n fenicsproject -c conda-forge/label/fenics-dev  -c conda-forge fenics SVMTK h5py
conda activate fenicsproject

h5py should also be installed, or else there might be conflicts between the version of h5py that is installed with fenics and the one that is installed by meshio (listed as a pip-installable dependency).

Installation

The panta-rhei package itself may be installed using pip,

pip install panta-rhei

or by cloning the repository and running the following command in the root directory:

pip install -e .

Running tests

Tests depends on the Pixi, a python package manager tightly integrated with conda. It can be installed by running

curl -fsSL https://pixi.sh/install.sh | bash

The tests can be run by running the following command in the root directory:

pixi run test
