GRAPE (GRids about Airfoils using Poisson's Equation) is a
two-dimensional elliptic grid generation code that was developed by Reece
Sorenson at NASA Ames Research Center for use with isolated airfoils. This
version of GRAPE was modified by Rod Chima at NASA Glenn Research Center for
use with turbomachinery blades, and can be used to generate grids for the
RVCQ3D turbomachinery analysis code.
Four test cases are included with GRAPE: An isolated
airfoil, Goldman's turbine vane, a high-speed centrifugal compressor blade, and
NASA compressor rotor 37.
GRAPE requires a Fortran 90 compiler and PLOT3D-compatible
CFD visualization software. It is usually run on Linux systems, but can be run
on a PC or Mac.
