Save fespace array to HDF5

Dear developers,
is it possible to store the problem solutions and meshes to HDF5 format, since it is included in the required packages for the installation? It would be extremely useful and faster than writing on txt files…
Thank you so much in advance,
best regards

  1. it’s actually not required, you can disable it --with-hdf5=no during ./configure
  2. there is an example in examples/plugin/iohd5-beam-3d.edp
  3. if you use PETSc/SLEPc and have HDF5 support, you can add to your parameters -ksp_view_solution hdf5:my_sol
