Staggered-grid finite-difference acoustic modeling with the Time-Domain Atmospheric Acoustic Propagation Suite (TDAAPS). Page: 4 of 107
This report is part of the collection entitled: Office of Scientific & Technical Information Technical Reports and was provided to Digital Library by the UNT Libraries Government Documents Department.
This document is intended to serve as a users guide for the time-domain atmospheric
acoustic propagation suite (TDAAPS) program developed as part of the Department of
Defense High-Performance Modernization Office (HPCMP) Common High-Performance
Computing Scalable Software Initiative (CHSSI). TDAAPS performs staggered-grid finite-
difference modeling of the acoustic velocity-pressure system with the incorporation of spa-
tially inhomogeneous winds. Wherever practical the control structure of the codes are
written in C++ using an object oriented design. Sections of code where a large number of
calculations are required are written in C or F77 in order to enable better compiler optimiza-
tion of these sections. The TDAAPS program conforms to a UNIX style calling interface.
Most of the actions of the codes are controlled by adding flags to the invoking command
line. This document presents a large number of examples and provides new users with the
necessary background to perform acoustic modeling with TDAAPS.
Here’s what’s next.
