preCICE v2.1.0 Release Notes

    • ➕ Added MPI version detection and print it during the CMake configuration.
    • ➕ Added a new action to sum up data values, action:summation.
    • ➕ Added check for only allowing watchpoints on a provided meshes.
    • ➕ Added check for the coordinates of configured watchpoints. They have to match the dimensionality of the <solver-interface>.
    • ➕ Added check to prevent <use-mesh> from the same participant.
    • ➕ Added control flow checks to C bingings.
    • ➕ Added many tests for the communication abstraction.
    • ➕ Added option to make a convergence measure strict. It has to converge then and leads to a premature simulation stop if not.
    • ➕ Added parallel support for Eigen RBF mapping.
    • ➕ Added platform-specific defaults of the loopback interface name to the network attribute of socket connections.
    • ➕ Added reset of written data 0 in advance() to simplify detection of missing write data calls.
    • ➕ Added several checks to prevent that false API usage leads to complicated quasi-Newton assertions.
    • ➕ Added support for planar quads based on triangulation, needed, for instance for nearest-projection mapping. Quads will be split along the shortest diagonal to minimize the mapping error. Note that this triangulation will be visible in configured mesh exports.
    • ➕ Added tests which build solverdummies and tests which run them in various configurations.
    • ➕ Added tooling to prevent changelog conflicts.
    • ➕ Added warning when configuring m2n as mpi when preCICE is compiled with OpenMPI. This is known to cause connection issues.
    • 👍 Allowed multiple convergence measures of same coupling data.
    • 🔄 Changed com::MPIDirectcommunication to work only for Master-Slave connections.
    • 🔄 Changed test setup to a simpler and consistent version using the new testing::TestContext. Tests now require to run on 4 MPI ranks. They will still compile but not run when MPICommunication=OFF.
    • 🔄 Changed the CMake FindNumPy module to only consider information based on the selected python interpreter.
    • 🔄 Changed the minimum required PETSc version to 3.12, which delivers consistent results across platforms.
    • ✅ Disabled tests based on MPIPorts and MPISinglePorts when using Open MPI.
    • ✅ Enabled RBF-based tests in partiton unit-tests and serial integration tests.
    • 🌲 Extended iteration logging by total and dropped quasi-Newton columns.
    • Extended title headers of convergence and iteration files by measure abbreviation.
    • 🛠 Fixed MPIPorts and MPISinglePorts not always closing ports.
    • 🛠 Fixed SocketCommunication setting up a port and writing connection info even if there are no requesters.
    • 🛠 Fixed compatibility with Boost 1.73.0.
    • 🛠 Fixed memory leaks and hanging communication when not calling precice::SolverInterface::finalize().
    • 🛠 Fixed memory leaks in C bindings.
    • 🛠 Fixed memory leaks in Fortran bindings in case of missing call toX_finalize().
    • 🛠 Fixed memory leaks when using petrbf mappings in some conditions.
    • 🛠 Fixed occasional errors when using PETRBF with a preCICE-managed MPI Communicator.
    • 🛠 Fixed over-subscription error when executing the tests with recent versions of Open MPI on less than 4 physical cores.
    • 🛠 Fixed silent truncation of numeric values in the config with C locales using decimal comma. The parser now always uses the locale en_US.UTF-8.
    • 🛠 Fixed target test_install requiring CMake version 1.13.
    • 🛠 Fixed value semantics of precice::SolverInterface.
    • Improved all error messages.
    • 👌 Improved readability of relative convergence measure INFO logs.
    • 🔨 Refactored com::Communication handling of rank adjustments.
    • 🔨 Refactored cplscheme::BaseCouplingScheme and derived classes. Introduce cplscheme::BiCouplingScheme.
    • 🔨 Refactored mesh::BoundingBox into seperate class.
    • ✂ Removed m2n:mpi-single, which never worked outside tests.
    • ✂ Removed convergence file logging for min-iterations convergence measure.
    • ✂ Removed deprecated and untested Manifold Mapping. API functions hasToEvaluateSurrogateModel and hasToEvaluateFineModel remain as nop stubs.
    • ✂ Removed logging of average convergence rates.
    • ✂ Removed support for CPP and CPPFLAGS environment variables.
    • 🚚 Renamed a few functions of the Fortran bindings for consistency with the C++ API. This does not break backwards compatibility, but the previous functions are now considered deprecated and will be removed in v3.
    • ✂ Removes the summary of event timing when preCICE finalizes and writes it to the file precice-PARTICIPANT-events-summary.log instead.
    • 🔧 Restricted the configuration of WatchPoints to provided meshes.
    • ✅ Split multi-setup integration tests into multiple single-setup tests.
