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), 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/.
