Using Graphics Accelerators in Modeling Nonlinear Ultrasonic Beams on the Basis of the Westervelt Equation

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

The problem of accelerating algorithms is considered for calculating the effects of diffraction, nonlinearity, and absorption in modeling high-intensity ultrasonic beams using the nonlinear Westervelt equation. The results from calculations using graphics accelerators (graphical processing units) are compared to ones obtained with a central processing unit. The performance of the algorithm is analyzed as a function of the parameters of the input data.
