UBC Model – Mesh Designer
Add geological constraints to UBC-GIF models
Add geological constraints to UBC-GIF models and build UBC-GIF MAG3D and GRAV3D voxel models and run time control files for any ModelVision model.
An Optional Extension for Encom ModelVision
The optional UBC Model-Mesh Designer extension for Encom ModelVision makes it easy to prepare and run UBC-GIF GRAV3D and MAG3D smooth inversions. The solid models are converted to mesh models by assigning properties to each mesh cell that falls inside a body. The density and susceptibility of that body are assigned to each cell.
The standad UBC tools can be used to visualise the results of the smooth inversion or integrate the inversion results with other models and data sets in Encom PA. Encom ModelVision inserts geological controls into the UBC-GIF smooth inversion and populates the entire model with physical properties.
UBC-GIF stands for the University of British Columbia, Geophysical Inversion Facility and developed the 3D voxel inversion programs MAG3D and GRAV3D. These programs are available from Pitney Bowes Software under licence from the University of British Columbia.

Easy Mesh Design
A dynamic mesh designer provides full control over the mesh density for the core and padded zone of the 3D model. The relationship between the mesh and the geological model is visualised in 3D and modified to ensure optimum coverage of the core zone. The mesh density can be easily modified to allow rapid prototype testing in MAG3D and GRAV3D, this ensures all parameters are optimised prior to running a high resolution inversion that may run for hours or days.
Automated Population of the 3D Mesh
Encom ModelVision models hold both the magnetic susceptibility and density properties of the geological bodies making it easy to create either a UBC MAG3D or GRAV3D model. Properties are assigned to the mesh on the basis that each voxel is dominant within a particular body within the model, and the background property is assigned to all unpopulated voxels. Any changes that are made to the input model are then easily updated in the UBC-GIF voxel model.
Run MAG3D and GRAV3D from Encom ModelVision
Once the mesh design has been completed, the mesh, properties, data and terrain are automatically exported to create each of the files required to run the UBC-GIF codes. Encom ModelVision will start the GRAV3D or MAG3D interface programs, with all fields populated with the relevant file names.
Import Geological Models
Encom ModelVision has the ability to import 3rd party geological models in GoCAD, 3D DXF and mine planning formats making it a relatively simple job to assign properties and build constrained UBC-GIF inversion models.
