The development repository for the deal.II finite element library.

Project mention: Good examples of C++ source code for math oriented software development? | /r/cpp_questions | 2023-06-17

For what concerns FEM, I think DealII is a great library with an outstanding documentation and tutorial: https://www.dealii.org/

DFT-FE: Real-space DFT calculations using Finite Elements

Project mention: MATLAB Kernel for Jupyter Now Works on Windows | /r/matlab | 2023-06-27

For instance, I've got tons of open-source tools ( MOOSE, Dakota, Uintah, Firedrake, MUESLI, LAMMPS, DFT-FE ) that I use on my WSL that aren't really compatible with Windows. So I'd prefer (need?) to stay in WSL to produce the Jupyter notebooks with Matlab. I suppose I could probably install a Linux distro of Matlab on my WSL, but then I've got two installations of Matlab eating up disk-space.
