Real-time simulation and visualization using pre-calculated fluid simulator states

We present our extension for structured fluid simulators and solvers widely used in computer graphics and simulation applications. It is based on storing pre-calculated fluid simulator states (FSS). The simulation using our extension is based on partial computation with synchronous utilization of pre-calculated fluid simulator states stored on disk device. We have incorporated this concept to real-time simulation and visualization system of combustion processes in pulverized coal boilers. The system is based on a simple fluid simulator and a coal particle system. We compared features between classical approach of storing data sets and saving the output of visualization to common movie files formats. Furthermore, we have performed measurements of overall acceleration and disk space requirements. The disk space requirements are in orders less demanding than the ones needed for saving corresponding data sets. This allows better scalability and storing and replaying results of complex tasks with large grids and/or ten thousands of particles.
