  Over the past 30 years, the cell-centred finite volume method has developed
to become a viable alternative to the finite element method in the field of
computational solid mechanics. The current article presents an open-source
toolbox for solid mechanics and fluid-solid interaction simulations based on
the finite volume library OpenFOAM. The object-oriented toolbox design is
outlined, where emphasis has been given to code use, comprehension, maintenance
and extension. The toolbox capabilities are demonstrated on a number of
representative test problems, where comparisons are given with finite element
solutions.
