TALK=T;RUN(1,1) DISPLAY Simulation of laminar steady flow around an inclined tube in a uniform stream. The tube is presented in the form of two coaxial cylinders. The external cylinder has the material with number 198 and the internal cylinder has the material of domain. The grid is cartesian and rather coarse (20*20*20), but the flow follows the curved surface smoothly because the SPARSOL 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. This file contains a macro of commands which cause the Viewer (when the macro button is pressed) to display contours automatically.
