Some of the HMM material here forms part of a workshop developed with colleagues in the HMM Workshop (Montgomery, Furze, Baxter-Chapman & de Boer, University of Leeds; doi:10.5281/zenodo.21834798), itself released under MIT and CC BY 4.0. The scientific libraries used — FEniCS, NGSolve, PETSc and others — remain under their own licences, as do any externally sourced figures, which are credited where they appear.
