1 a system of wires through which electricity is connected to different power stations across a region: --
the national grid
2 a pattern of squares with numbers or letters used to find places on a map --
3 a pattern of lines marking the start of the track in motor racing (= a sport of racing very fast and powerful cars around a track): --
4 a pattern of horizontal and vertical lines that cross each other to make a set of squares --
a power grid

All grids were constructed with 27-node brick elements with triquadratic interpolation.
Two stainless steel grids were employed, a 2.54 em mesh and a 5.08 cm mesh.
The turbulence corresponding to (2.7) is more nearly analogous to three-dimensional turbulence produced by wind-tunnel grids, since they cannot impart arbitrarily large momenta either.
The transformation of the mechanical and magnetic quantities between the different grids is now realized by multigrid transfer operators.
Squares are 500 m x 500 m and represent fully mapped grids; diagonal lines are causeways.
The property rights over electricity grids are not limited by regulations, and there are only a few connections (with small capacity) between the national grids.
The grids were constructed from polypropylene, a material which floats in water.
After truncation a t finite terms the equations are approximated by finite differences in i j with smaller grids for smaller ij.
