This proposal works on grids and constituents organized in a multidimensional plane ruled by phonological principles , which control the projections onto a metrical grid . In principle , this tool can be used to regrid any logically rectangular gridded field onto a spherical grid . Once the movement , such as swinging the arm or wiggling the foot , is recorded , it is overlaid onto a sound grid . In some cases the model may be mapped onto a genealogical grid , but that is not an essential feature of a kinship system . In a numerical model , the evolution of the ejecta and ISM gas , fit onto a computational grid , is followed over time , by using the conservation equations of mass , momentum and energy .
