TALK=F;RUN( 1, 1) ************************************************************ Q1 created by VDI menu, Version 2007, Date 26/09/07 CPVNAM=VDI;SPPNAM=Core ************************************************************ Echo DISPLAY / USE settings DISPLAY Simulation of laminar steady flow around a sphere in a uniform stream at a Reynolds number of 40 . The grid is cartesian and rather coarse (18*18*31), but the flow follows the curved surface smoothly because the PARSOL (i.e. cut-cell) technique is used. The fluid is atmospheric air, treated as incompressible. The variables computed are: * p1, the pressure, * u1, the x-direction velocity, * v1, the y-direction velocity, and * w1, the z-direction velocity.
