Troubleshooting artifacts in surfaces and 3D grids (including fault cutoff lines)
When performing the Construct Surfaces step in the structural modeling workflow, or when editing fault cutoff lines, under rare circumstances you may see artifacts in the resulting surfaces or the simultaneously created QC grid
.
The structural modeling workflow in JewelSuite Subsurface Modeling is continuously being upgraded through improvements to existing functionality and by providing new functionality. This new functionality, and with it the changes in how you use the software, may introduce some unexpected artifacts at various stages in the workflow. For example, the input data may not have been prepared correctly for use with the provided algorithms. It is also possible for you to apply the functionality in such a way that you unwittingly create an undesired effect.
You can use the Diagnostic Tool (Modeling > Faults > Tools) during different stages of the modeling process, to run multiple quality tests on the tri-meshes contained in your fault model. For information on the Diagnostic Tools, see Using the Diagnostic Tool.
This section addresses several of these cases in 3D structural modeling (including fault cutoff lines). It also addresses artifacts in (QC) grids, because some artifacts typically manifest themselves there, while their root cause may lay earlier in the workflow. The topics describe the type of issue you may encounter and the causes of the artifacts and ways to remove them, to help you to create your desired structural model and 3D grid.
