Finite volume solver for incompressible multiphase flows with surface tension.
Key features:
- implementation in C++14
- scalability to thousands of compute nodes with the Cubism library for distributed computing on structured grids
- coroutines to enable encapsulation in the block-wise processing framework
- fluid solver based on SIMPLE or Bell-Colella-Glaz methods
- conservative split PLIC advection solver
- particle method for curvature estimation improving the accuracy at low resolutions [online demo] [4]
- coalescence prevention [online demo] [8]

C++14, CMake
Optional dependencies: MPI, parallel HDF5, python3, python3-numpy
Bundled optional dependencies: hypre, eigen, overlap, vofi, fpzip
Follow instructions from deploy/README.md to prepare environment and install dependencies.
Configure, build, install and run tests:
cd src
make -j4
make test
Instead of building the code in your system, you can build and run a Docker container
docker build github.com/cselab/aphros --tag aphros
docker run -i aphros
This is a minimal build without dependencies and tests.
cd src
APHROS_PREFIX=PREFIX make -f Makefile_legacy install
where PREFIX is the installation location (e.g. ~/.local).
