Introduction
This process splits block model cells at cell boundaries and recalculates the IJK value.
|
This process will only work correctly with rotated model data If *PROTO has the same origin and rotations as *IN, but can have different rotated origins (X0, Y0, Z0) and different local origins ([XYZ]MORIG) |
How to use
Using this process a block model can be transferred to a new block model prototype, with a different origin, different cell size and different number of cells. The user must ensure that the new prototype definition includes all cells in the existing model.
