John F. Gibson <[EMAIL PROTECTED]> described the package as follows: License: gpl Other License: Package: Channelflow: a fluid-flow simulator System name: channelflow Type: non-GNU Description: Channelflow is a direct numerical simulation of the time-dependent Navier-Stokes equations, written in C++. It's of interest to researchers in fluid mechanics. Math/physics details: Channelflow simulates incompressible fluid flow in a rectangular box, with no-slip boundary conditions on the upper and lower surfaces of the box, and periodic boundary conditions in the stream and spanwise directions. Channelflow uses a spectral discretization in spatial directions (Fourier x Chebyshev x Fourier) and finite-differencing in time, on primitive variables (3d velocity and pressure). The mathematics are based on the spectral channel-flow algorithm in Section 7.3 of "Spectral Methods in Fluid Dynamics", by Canuto, Hussaini, Quarteroni, and Zang, Springer Verlag, 3rd ed. History, motivation, plans: I wrote channelflow from 2000-2003 for my Ph.D. thesis research. (There is a widely-used Fortran implementation of the basic algorithm, but I found it inscrutable and not flexible enough for my research.) I've distributed it from my department's website for several years. Now I plan to improve documentation and packaging, write a simple GUI, distribute more broadly, get feedback from users, and coordinate others' modifications and ports to other platforms. At this point, channelflow is an edit/compile/run, console-based application. A slightly-out-of date version is at ftp://mae.cornell.edu/pub/users/gibson/channelflow-0.9.5.tgz Other Software Required: channelflow requires fftw-2.x (www.fftw.org) some advanced features require Octave (www.octave.org) but currently those are commented out Other Comments: _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/ _______________________________________________ Savannah-hackers mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/savannah-hackers
