How To Generate a Shell Around a Surface

Objective:

To generate a shell around a specific surface to represent for example a fault zone.

Geological Model faults in Leapfrog [Geo/Works/Geothermal] are represented as 0 thickness surfaces.

Resolution:

Using the Distance Function to generate a constant thickness around a single or multiple surfaces.

1. Built or import the surfaces.
   
2. In the Numerical Models Folder select New Distance Function
   
3. Select Which objects to use
   
4. Set a decent resolution for the problem at hand in the Buffers tab
   
5. Display and use the results
   

In this example a volume with a 50 distance has been generated around the faults to be used for other tasks.

Notes:

• A smaller resolution increases calculation time.
  • Smaller resolution also means more triangles. This may not be optimal when exporting to other software packages.
• It could be useful to run each object individually and perform post cutting using Mesh Operations and/or a Geological Model.
