# chammp # ====== # # This directory contains items relating to the numerical solution # of the shallow water equations in spherical geometry. # The shallow water equations are used as a kernel for both # oceanic and atomospheric general circulation models and # are of interest in evaluating numerical methods for weather # forecasting and climate modeling. The DOE Computer Hardware, # Advanced Mathematics and Model Physics (CHAMMP) program # is interested in the development of new mathematical methods # for these problems. To promote this developmet, a set of # test cases has been proposed and example software and reference # solutions are provided. file shallow.tex for LaTeX document containing benchmarks and results pertaining to , shallow water equation solution methods. , To retrieve from netlib type: "send shallow.tex from chammp" age Last updated: 10/1/93 file shallow.bib for LaTeX bibliography file of articles and reports dealing with , the test cases. , To retrieve from netlib type: "send shallow.bib from chammp" age Last updated: 10/1/93 file stswm.tgz for NCAR spectral transform shallow water model and documentation. , This code computes reference solutions for all test cases in , [Reference solutions generated by this code are available by , anonymous ftp from ftp.ucar.edu (IP address 128.117.64.4) , in directory chammp/shallow.] by Authors J.J.
