Abstract
This paper proposes a fluid simulation method with a surface tension effect using interparticle interaction forces based on a position based fluid. Behavior of fluid is efficiently calculated by using SPH (Smoothed Particle Hydrodynamics), which represents fluid as particles, and the method appends the surface tension force as the interaction force between the particles. Also, interaction between fluid and solid boundary is considered by adding solid particles along the boundary. Furthermore, this paper propose an instinctive controlling method for liquid shape, such as a water drop, by using a contact angle.
