Cascade is a C++/Python library developed to propagate the evolution of large number of orbiting objects while detecting reliably close encounters and collisions. It is coded in modern C++20 with focus on the efficency of the underlying N-body simulation with collision/conjunction detection.

Install conda env:

conda env create -f cascade_devel.yml
conda activate cascade_devel

Compile:

mkdir build
cd build
cmake ../ -DCMAKE_INSTALL_PREFIX=$CONDA_PREFIX -DCMAKE_PREFIX_PATH=$CONDA_PREFIX -DBoost_NO_BOOST_CMAKE=ON -DPython3_EXECUTABLE=$CONDA_PREFIX/bin/python -DCASCADE_INSTALL_LIBDIR=lib -DCASCADE_BUILD_PYTHON_BINDINGS=yes -DCMAKE_BUILD_TYPE=Debug
make install
