Backwards-compatible fork of SAMRAI 2.4.4 containing some additional patches, both for improving performance and for fixing problems with modern compilers.
IBSAMRAI2 assumes that the C++ compiler's default language standard is C++11 or
newer. This is the case for all major compilers released after 2017. If you must
compile IBSAMRAI2 with an older compiler then you must add -std=c++11 or
equivalent to CXXFLAGS. See ./configure --help for more information in
setting up compilation flags.
