Fault model
Fault model - contains 3D fault-network models built from fault picking (used by structural modeling).
Right mouse button on the icon allows to:
- Create new
- Add folder
Right mouse button on a fault model additionally allows to:
- Open
- Rename
- Convert to Multi-Z surfaces
- Colorize
- Delete
- Extract fault data
Right mouse button on an individual modeled fault surface allows to:
- Set color
- Extract fault data
Create new opens the Fault Modeling wizard.
Extract fault data
Choose Extract fault data on a fault model to create one point set from all of its modeled fault surfaces, or on an individual modeled fault surface to include only that surface.
In the Extract fault data dialog, enter an Output name and adjust Add source fault name as attribute, Remove duplicate points and Skip faults with empty geometry (report in results) as needed. Both Run and Save create the point set under Data Manager → Points. Save to workflow adds the configured extraction to the project workflow without creating the point set immediately.
Fault Modeling Wizard
The Fault Modeling wizard builds modeled fault surfaces from interpreted fault data stored in the Data Manager. At the top of the dialog choose the Domain (Depth or Time) and enter a Name for the model. The workflow is organized into three tabs.
Fault Inputs
Select which faults take part in the model and how their data is used.
- Available Inputs (left panel) lists the faults from the Data Manager. The Faults and Multi-Z surfaces checkboxes filter what is shown.
- Use Add → and ← Remove to move items between the available list and the Selected Faults table.
- The Selected Faults table has columns Fault Name, Points, Sticks, Maps, Markers and Fault Type.
Each data-type cell (Points, Sticks, Maps, Markers) sets how that input is used. Only data types actually present on the fault are editable:
- No data (grey) - the data type is not used.
- Soft (green) - guiding constraint; the surface may deviate slightly for a smoother result.
- Hard (blue) - strict constraint; the surface honors this data as closely as possible.
The Fault Type column (Normal, Reverse, Strike-slip, Unknown, Strike-slip + Normal offset or Strike-slip + Reverse offset) is read from each fault's stored type and can be edited here. See Assign Fault Type for setting the type directly on the fault object.
Surfaces
Define surface-generation parameters, one row per selected fault. Columns: Fault Name, Step X, Step Y, Smoothing (%), Shape, Extend H and Extend V.
- Step X / Step Y - grid sampling in project units (meters or feet).
- Smoothing (%) - higher values give a smoother surface (0-100).
- Shape - Ellipse, Rounded boundary or Input shape. Input geometry is always preserved.
- Extend H / Extend V - how far the surface extends beyond the input data, in project units. Disabled when Input shape is selected.
Fault Intersections
Intersections between selected faults are detected automatically. For each pair the table shows Fault, Intersects With and Dominant Fault. Choose the dominant fault from the drop-down: the dominant fault continues through the intersection and the other fault is truncated.
Running and Saving
Select the Fault Inputs, Surfaces and Fault Intersections tabs directly. Run generates the modeled fault surfaces using the selected data constraints, surface parameters and intersection rules, stores the model under Data Manager → Faults → Fault model, and keeps the wizard open. It is enabled after you provide a unique model name and select a fault with at least one input type set to Soft or Hard, or select a Multi-Z surface. Save stores the current model settings in the same branch without recalculating and also keeps the wizard open. A calculated model is visible in the 3D View and can be reopened with Open.
Save to workflow adds the current settings as a Fault Modeling task in the project workflow without running the model. Use Close to exit the wizard.
Running or saving a fault model does not automatically publish its per-fault surfaces under Multi-Z surfaces. To publish them, right-click a calculated model in the Data Manager and choose Convert to Multi-Z surfaces. After this explicit conversion, each later run of the same model refreshes its Multi-Z surfaces. Multi-Z surfaces already stored by older product versions are preserved.
