Version v2023.03.0 -- Release date 2023-03-29

This release contains ...

  • Important Notes:
    • Spheral now requires C++ 14
    • Spheral C++ libs are compiled into a single library (Spheral_CXX)

Notable changes include:

  • New features/ API changes:

    • New Discrete Element Model (DEM) physics package with linear-damped spring approach.
    • Adding a CUDA smoke test that can be called from the Spheral python API.
    • NVCC / CUDA 11 gitlab-ci jobs.
    • ATS default filters for non-MPI, debug and CUDA builds are injected into spheral-atstest script.
    • Latest Develop docker containers hosted on ghcr.io/llnl/spheral:latest.
    • External / offline builds are tested through github actions.
    • New polyhedral gravity solver.
    • Improved DEM timestep choice, so that points that do not overlap do not overly constrain the timestep.
    • Point potential gravity solver can now have non-unit metrics.
    • Pair-max damage algorithm now decouples points in different NodeLists or with different fragmentIDs.
    • Added direct support for FacetedVolumes to FileIO interface.

  • Build changes / improvements:

    • The C++ library interface is compiled into a single Spheral_CXX library.
    • Previous Spheral C++ libraries are still CMAKE targets, but are "ojbect" libraries.
    • ATS bumped to version 7.0.9 for blueos smpi option support.
    • Eigen bumped to 3.4.0 for NVCC compatiblity.
    • C++ flag suppression is gaurded with build time CMake generators to only apply to C++ compilers.
    • Python runtime libraries are now managed through Spack / tpl-manager.
    • Added ENABLE_NAN_EXCEPTIONS (default OFF) Cmake flag to raise an exception when a NAN occurs (Gnu only).
    • Byte-compiling python installed in virtual spheral environment.
    • Invoking spheral no longer byte-compiles Python imported in a spheral script.
    • HDF5 links as a shared library. Static lib usage can be forced with ENABLE_STATIC_TPL.

  • Bug Fixes / improvements:

    • spheral-atstest scripts always point to locally installed ATS instance.
    • gitlab-ci report-results script for analyzing ATS CI runs.
    • Support for offline Spheral builds (provided TPLs are installed).
    • Fixes for restarting without regenerating the original node positions in the Python script.
    • Protected from division by zero in DEM when points coincide.
    • Corrected support for minimum pressure (intact and damaged) with porous materials.
    • Removed term driving damaged material to the reference density in solid hydros.
    • Added verbose flag to EquationOfState::specificThermalEnergyForPressure so users can see how the iterative search proceeds.
