    Efficient Simulation of Spatio-temporal Dynamics in Ultrasonic Resonators 
    Alonso-Jordá, Pedro; Peinado Pinilla, Jesús; Pérez Arjona, Isabel; Sánchez Morcillo, Víctor José (Springer Verlag (Germany), 2011)
    The simulation in computers of the evolution of pressure and temperature inside a cavity when acoustic energy is injected results in a very stiff and high time consuming application. The split-step method used for the ...
