NavierStokes solution on the CYBER203 by a pseudospectral technique
Abstract
A threelevel, timesplit, mixed spectral/finite difference method for the numerical solution of the threedimensional, compressible NavierStokes equations has been developed and implemented on the Control Data Corporation (CDC) CYBER203. This method uses a spectral representation for the flow variables in the streamwise and spanwise coordinates, and central differences in the normal direction. The five dependent variables are interleaved one horizontal plane at a time and the array of their values at the grid points of each horizontal plane is a typical vector in the computation. The code is organized so as to require, per time step, a single forwardbackward pass through the entire data base. The oneand twodimensional Fast Fourier Transforms are performed using software especially developed for the CYBER203.
