Therefore, the case considered is the 1d tangential laminar flow of an incompressible fluid between two coaxial cylinders of radius RADI and RADO, the outer one of which is rotating with an angular velocity of OMEGO. This case provides a test, for NX>1, of the U1 radial diffusion terms and the wall boundary treatment with RINNER=0. The analyical solution for the tangential velocity is U1=OMEGO*GRADO**2*(GRADI**2-GR**2)/[GR* (GRADI**2-GRADO**2)] where GR is the radius.
