Paul Swarztrauber and Roland Sweet, National Center for Atmospheric Research, have developed a package of subroutines for solving a modified Helmholtz equation with simple boundary conditions on a rectangle in any of five coordinate frames. Because problems of this type arise frequently and because the testing of such a package is not trivial, five federal laboratories collaborated in certifying this package. This report documents the results of the certification effort. Although some difficulties were encountered during testing, the certification team judged the package to be good mathematical software. The team particularly commends its design, which permits users to communicate with it in familiar terms without having to grasp the mechanics of the discretization procedure.
