Grid Space Models
Even more information on grid space modeling;
"..Simulation models may include a model of a space that is inhabitated by objects. One particular type of a space model is the two-dimensional discrete Euclidean space, also called grid space. Grid space models, which may also be one- or three-dimensional, can be considered as simplifications, or abstractions, of the real space.."
