This case directory is an implementation of the Modified Lid Driven Cavity
case of Shi et al (T. M. Shih, C. H. Tan, and B. C. Hwang, “Effects of
grid staggering on numerical schemes”,Int.J.Num.Methods in Fluids, vol. 9, pp.
193 – 212, 1989) as described in the paper "Implementation of a Modified
Lid-Driven Cavity in OpenFOAM" (G.Tabor, OpenFOAM Journal Vol X etc).

The characteristic lid speed is set as variable 'boxVel' in
constant/transportProperties whilst the dimension of the box and the mesh
resolution is set in constant/boxDimensions. These and the kinematic viscosity
are currently set to give Re=3 but can be modified.

This version works with OpenFOAM (OpenCFD Ltd) v2106 and v8.
