OPM

Within the OPM release 2021.10, some files in opm-common miss include statements. While on some systems such as Ubuntu 20.04, the corresponding headers are included implicitly, explicit includes are required on other systems such as Ubuntu 21.10. To add the includes, apply the patch

• opm_common_2021_10.patch in your directory containing opm-common

  patch -p1 <../dumux/patches/opm_common_2021_10.patch

dune-istl

If the AMGBackend should be used without SuperLU as coarse grid solver, it can be benefitial to decrease the corresponding tolerance. To do so, apply the patch

• istl-2.6.patch in your directory containing dune-istl 2.6

  patch -p1 <../dumux/patches/istl-2.6.patch
