Studio 3 Block Modelling - Defining the Model

Before creating a model you must define the region it will represent and the size of the parent cells it will contain. You store this information in a model prototype file, which contains the following components:

Model Fields - DATAMINE requires the following numeric fields in every model and prototype file. Note that instead of east, north and elevation, Studio 3 uses the generic names 'X', 'Y‘ and 'Z'. This is because you can align models to a local grid instead of the true coordinate grid.

XMORIG, YMORIG, ZMORIG - XYZ origin of the model. Studio 3 sets the origin with respect to the corner of the first parent cell (and not its centroid).

XINC, YINC, ZINC - XYZ cell dimensions. If the model is not to contain any subcells then these three fields can be implicit (not stored on every record). This will reduce the storage space required by the model.

NX, NY, NZ - Number of model parent cells in XYZ. Studio 3 allows a value of one for modeling seams. The number of cells, in combination with the cell dimensions, defines the extent of the model.

XC, YC, ZC - XYZ cell center coordinates.

IJK - Code generated and used by Studio 3 to uniquely identify each parent cell position within the model. Subcells that lie within the same parent cell will have the same IJK value.

Attributes - In addition the model can contain any extra attribute fields necessary
