4.2.9. Merge (Interpolate) 3D models

This tool allows the user to merge multiple 3D models onto a given mesh. The operation can be done across meshes with different discretization. The main menu allows the user to specify simple grid transformations as well as interpolation parameters:

The following fields control the inverse distance interpolation:

\[\mathbf{\bar m} = \frac{\sum_{i=1}^{N} \mathbf{m_i}{r_i}}{\sum_{i=1}^{N} {r_i}}\]

\[{r_i} = \left[ (x(\bar m) - x(m_i))^{2} + (y(\bar m) - y(m_i))^{2} + \delta \right]^{1/2}\]

where x and y define the cell center location of model column m in the underlying mesh.

Options	Description
Maximum Interpolation Distance	Neighboring cells with active property values
Interpolation Points	Number of neighbors included in the weighted average
Threshold parameters	Smoothing factor
No-data-value	Fill values for air cells and empty model
Rotation center [X,Y]	Easting, Northing position of rotation center
Rotation angle	Rotation counter-clockwise from East
Translation [X,Y]	Grid translation distances
