Abstract:

The computer program FIDO Finite Difference Ocean acoustic model computes the real acoustic pressure via a finite- difference approximation to the undamped wave equation. with attenuation implemented by the insertion of an additional radiation condition term in sediment regions of the computation grid. The program is implemented in FORTRAN and is well suited to most supercomputer architectures. Both time-domain and continuous-wave versions are described. Input file formats are given along with two sample input files. Test cast solutions for standard benchmarks and other problems are presented and compared to analytic and coupled-mode solutions.
