-The [Deal.II v8.4.1](https://dealii.org) is the only supported version. Deal.II need to be compiled with the dependencies required to run the tutorial [step-18](https://www.dealii.org/8.4.1/doxygen/deal.II/step_18.html#ElasticProblemoutput_results), namely the following dependencies: MPI (MPICH or Intel MPI), PETSc (>3.6, 64bits), METIS (>4.0), MUMPS (>5.0), BOOST (>1.58), HDF5, LAPACK, MUPARSER, NETCDF, ZLIB, HDF5, and UMFPACK. Complete instructions can be found [here](https://dealii.org/8.4.1/index.html). The MPI support for DealII and its dependencies must be built with __MPICH__ (will not work with OpenMPI!).
