Implementation of a full SPH pressuer solver, using WCSPH and PBF, as well as an explicit viscossity, cohesion and adhesion model. For improves scene setup, the setting can be defined in a scene file, specifying the simulation parameters. Core project was build as part of a uni project.
Key Features
