Grid Calculation
This section demonstrates the basics of grid calculation. It contains the definition of a grid as well as a simple case of setup and calculation. Grid arithmetics - the combination of two or more grids - is explained, too.
More sophisticated aspects of noise mapping are illustrated in later chapters. For example Dynmap, which allows updating the grid depending on measurements, is explained in the chapter 
Noise Mapping. Furthermore segmented processing of grids is explained in the chapter Distributed Calculation.
It is advisable to work through the first sections of this chapter, at least Entering and Deleting Objects and Evaluation of Single Receivers, before dealing with grid calculation.
