NAME

showmdl - Shows the content of a disper input file converted back to velocity and density

SYNOPSIS

showmdl [ infile ]

DESCRIPTION

Compatible with Basic Seismic Utilities (BSU). Program gendis creates an input file with namelist data for program disper. While gendis requires a layered earth model specified in terms of velocities, densities, and control depths, the namelist produced is expressed in terms of shear modulus mu and Lame’s constant lame. Program showmdl reads an input file (typically called disper.d ) and recomputes the elastic constants in terms of velocity and densities for a human readable format. Fortran 77 Version.

NOTES

The last lines of output are the control points for the 1-D earth model, given as control number, depth, S-wave velocity, P-wave velocity, and mass density.

FILES

stdout

Output is simultaneously generated to stdout and a text file.

show.tmp

File which saves the text output.
