displace_block

displace_block receives any 3D field into its input port and outputs the same field translated in z according to a selected nodal data component of an input surface allowing for non-uniform fault block translation.

This module allows for the creation of tear faults and other complex geologic structures. Used in conjunction with distance to surface it makes it possible to easily model extremely complex deformations.

 

WARNING: When displacing 3D grids, especially those with poor aspect cells (much thinner in Z than X-Y), if the displacement surface has high slopes, the cells can be sheared severely. This can create corrupted cells which can result in inaccurate volumetric computation. In general volumes and masses are best computed before displacement.

 

Module Input Ports

• Input Field [Field] Accepts a volumetric field
• Input Surface [Field] Accepts a 2D surface grid with elevation nodal data. This type of grid is created by gridding and horizons and import raster as horizon.

Module Output Ports

• Output Field [Field] Outputs the displaced field
• Output Object [Renderable]: Outputs to the viewer.
