PolyMPS-An open source CFD solver based on Polygon walls in Moving Particle Semi-implicit (MPS) method

PolyMPS is a C++ code for numerical modeling of free-surface flow using the mesh-less moving particle semi-implicit (MPS) method from two different ways, namely, the incompressible and weakly-compressible approaches. Besides the conventional solid wall boundaries represented by discrete layers of wall and dummy (ghost) particles, boundary walls can be modeled by polygonal mesh of triangles, therefore providing flexibility to model the surface of three-dimensional complex-shaped bodies. The present code has a lightweight and efficient CPU implementation using OpenMP for research and practical applications, while providing reliable results.
