We present our original methodology for acceleration of
fluids simulation computed by structured fluid simulators
and solvers. The methodology is based on storing Pre
Calculated Fluid Simulator States (FSS) and organizing
them in hierarchical tree structures allowing incremental
solving, interactive replaying and modifications of
simulated tasks. Thus, the parameters and boundary
conditions of the simulation can be real-time modified
during replaying. The simulation using our methodology
is based on only partial computation with synchronous
utilization of pre-calculated fluid simulator states stored
on hard disk storage.
We have incorporated this concept into 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 have made comparison of FSS features with classical
approach of storing data sets and saving the visualization
output to common movie formats. Furthermore, we have
performed measurements of overall acceleration of
simulation and discussed disk space demands. The disk
space requirements are in orders less demanding than the
ones needed for storing corresponding data sets. This
allows better scalability and storing and interactive
replaying simulation results of complex tasks with large
grids and/or ten thousands of particles.
