Intrinsic properties of geologic media are attributed to grid cells in STOMP via the association of properties with rock/soil types and then the association of those rock/soil types with grid cells. A computational domain with homogeneous geologic intrinsic properties can be created in STOMP by defining a single rock/soil type and then associating that rock/soil type with all the grid cells. A computational domain with fully heterogenous geologic intrinsic properties can also be created in STOMP by specifying a unique rock/soil type for every grid cell. The central concept in specifying intrinsic properties of geologic media to grid cells in STOMP is to first associate those properties with rock/soil types and then specify the distribution of rock/soil types to the grid cells. The specification of rock/soil types with grid cells will be referred to as rock/soil zonation.
