openPSTD: The open source pseudospectral time-domain method for acoustic propagation

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)

Abstract
An open source implementation of the Fourier pseudospectral time-domain (PSTD) method for computing the propagation of sound is presented, which is geared towards applications in the built environment. Being a wave-based method, PSTD captures phenomena like diffraction, but maintains efficiency in processing time and memory usage as it allows to spatially sample close to the Nyquist criterion, thus keeping both the required spatial and temporal resolution coarse. In the implementation it has ...
