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 ...

本程序源自贝尔法斯特女王大学（1969-2018年）所持有的CPC程序库。本文档介绍了针对建筑环境应用而开发的声波传播的傅里叶伪谱时域（PSTD）方法的开源实现。作为一种基于波的方法，PSTD能够捕捉诸如衍射等现象，同时在处理时间和内存使用上保持高效，因为它允许空间采样接近奈奎斯特准则，从而保持所需的空间和时间分辨率相对粗糙。在其实施过程中，它具有...
