Lid-driven cavity flow benchmark v-velocity values from Ghia, U. K. N. G., Ghia, K. N., & Shin, C. T. (1982), Journal of computational physics, 48(3), 387-411.
# Ghia, U. K. N. G., Ghia, K. N., & Shin, C. T. (1982).
# High-Re solutions for incompressible flow using the Navier-Stokes equations and a multigrid method.
# Journal of computational physics, 48(3), 387-411.

# TABLE II
# Results for $v$-Velocity along Horizontal Line through Geometric Center of Cavity
# [Note: The velocity for Re = 400 and point (x,v) = (0.9063,-0.23827) is probably wrong]
