The two full wave Acoustics Solvers (P-ACOUSTICS) encompass 1) a Graphics Processing Unit (GPU) and OpenMP accelerated non-linear FDTD method with an extended Westervelt-Lighthill equation applied to adaptive rectilinear meshes with inhomogeneous PML boundary conditions and 2) a fast near-field method combined with the hybrid angular spectrum approach (FNM-CHASM) to simulate complex wave propagation inside inhomogeneous tissue distributions and to rapidly calculate pressure distributions for applications such as focused ultrasound treatments. This is state-of-art in computational acoustics.
Precise ablation of a liver tumor located behind the ribs considering respiratory movements.
The novel ultrasound solvers account for pressure wave propagation, density variations and jumps, non-linearity, and diffusivity losses that occur in human tissue.
The FNM-CHASM solver offers near real-time simulations of acoustic propagation in inhomogeneous setups.
The P-ACOUSTICS solvers have been extensively validated and the associated uncertainties have been quantified using analytical solutions, benchmarks, and robotic 3D-scan hydrophone measurements in complex setups. Comprehensive documentation is available for Sim4Life.
