Fluid Simulation Program

In this paper a survey on the existing approaches to fluid modeling is performed. Approaches to modeling the fluid surface as well as to modeling streams with due account for hydrodynamic properties are considered. For the research, an approach Position Based Fluids is chosen. It allows simulating incompressible fluid represented as a system of particles of the same mass. Gravity force is affecting the fluid, the interaction between particles is considered and their collision with the boundaries of the container. Polygonal static objects are placed in the container for the fluid to collide with them. The application is developed with the use of CUDA technology, thus, most calculations are performed on GPU. A series of 25 experiments were performed with various amounts of particles and different static objects. In each experiment performance time of the particles’ update cycle is measured. Aside from the time spent on the particles’ update cycle in general, performance time of each operation of the cycle in particular is computed.
