Installation

A working installation of FEniCS (version 2019.1.0) is required to run dolfin_mech. To setup a system, the simplest is to use conda: first install miniconda (note that for Microsoft Windows machines you first need to install WSL, the Windows Subsystem for Linux, and then install miniconda for linux inside the WSL; for Apple MacOS machines with Apple Silicon CPUs, you still need to install the MacOS Intel x86_64 version of miniconda), and then install the necessary packages:

conda create -y -c conda-forge -n dolfin_mech fenics=2019.1.0 matplotlib=3.5 meshio=5.3 mpi4py=3.1.3 numpy=1.23 pandas=1.3 pip python=3.10 vtk=9.2
conda activate dolfin_mech

Now, if you only need to use the library, you can install it with:

pip install dolfin_mech

But if you need to develop within the library, you need to install an editable version of the sources:

git clone https://github.com/mgenet/dolfin_mech.git
pip install -e dolfin_mech/.
