The INS3D code solves the incompressible Naiver-Stokes
equations in three-dimensional generalized coordinates for
both steady-state and time varying flow. The equations are
formulated into a hyperbolic set of PDE using the method of
artificial compressibility. The convective terms are
differenced using an upwind biased flux-difference splitting.
The equations are solved using an implicit line-relaxation scheme.
The code is written for single or multiple-zone calculations. It
can utilize either pointwise continious zonal interfaces, or random
overlapped zonal interfaces if a PEGSUS interpolation database is
supplied. The flow solver contains pre-coded boundary conditions for
slip and noslip walls, symmetry planes, inflow and outflow boundaries,
and far-field boundaries.
The INS3D code is written in Fortran 77, with some extensions and
several routines which are written in C. The source code comes
ready to compile and run on either a Cray computer or a Silicon
Graphics workstation.
