Sonification of a Complex Computational Process: Computational Fluid Dynamics

A live demonstration of the real-time sonification of a complex numerical calculation of a computational fluid dynamics (CFD) simulation is to be performed. The CFD process is implemented in a Java programming environment using JSyn as the sound synthesis tool. A FM Formant Instrument (3 oscillators) is used as the main unit generator (a total of 26 instruments are used to represent computational cells in the domain). All parameters of the instruments, together with the envelopes of each sound event, are mapped directly from the computational process in real time. The computational process is iterative in nature, hence the listener experiences the unfolding of lengthy ``phrases'' which pan from left to right and represent the ``marching'' of the solver through the computational domain.
