Numerical modelling of acoustical processes by particles interaction
We propose the method to simulate acoustical processes in solid media using interacting particles placed in body-centered cubic lattice. Each particle interact with its neighboring particles according to attraction force defined by specific function for each material type. Particle dynamics is described by Newtons laws. The simulation model shows correctly such acoustical effects as wave propagation, reflection and resonant vibrations. The simulation algorithm is embodied in the program by means of parallel programming of OpenCL technology, which allows to speed up modeling. By time reversal approach we demonstrated ability to visualize pulse sound sources.
