horizons to 3d
The horizons to 3d module creates 3-dimensional solid layers from the 2-dimensional surfaces produced by gridding and horizons, allowing visualization of the geologic layering of a system. It does this by creating a user-specified distribution of nodes in the Z dimension between the top and bottom surfaces of each geologic layer.
The Z Resolution nodes can be distributed proportionally across geologic layers based on each layer’s fractional thickness relative to the total geologic domain. When using proportional gridding, at least the specified minimum number of cell layers will be placed in each geologic layer.
If any portions of the input geology are NULL, those cells will be omitted from the output grid. This can save memory and provides a means to cut along boundaries.
Ports
| Direction | Name | Type | Description |
|---|---|---|---|
| Input | Input Geologic Field | Field | The main geologic field to map to 3D. |
| Output | Output Field | Field | The geologic field mapped to 3D. |
Properties
| Property | Type | Description |
|---|---|---|
| Allow Run | Boolean | Determines whether the module is allowed to execute. Set to True to allow this module to run. |
| Execute | Button | Forces the module to run even when Allow Run has been turned off. |
Grid Settings
| Property | Type | Description |
|---|---|---|
| Grid Type | Choice: Non-Explodable, Standard | The type of grid to create. A Standard grid (default) produces one cell set per geologic layer, allowing layers to be separated with Explode and Scale. A Non-Explodable grid produces a single, more memory-efficient grid which cannot be exploded. |
Layer Settings
| Property | Type | Description |
|---|---|---|
| Z Resolution | Integer | Used as a guide for establishing the total number of cells in the model. The module could potentially produce more than the total. |
| Minimum Cells Per Layer | Integer | Establishes a minimum number of cells (in the Z direction) per layer. |
| Cells Per Layer | Integer | The cells (in the Z direction) per layer when using the selected Proportional Gridding option. |
| Proportional Gridding | Choice: Cells Per Layer, Proportional Z Resolution | When multiple geologic layers exist, cells are apportioned to layers in Z based on each layer’s average thickness over the total model domain, but further subject to the Min Cells Per Layer parameter. Actual Z Resolution may be higher than specified. |
| Minimum Layer Thickness | Double | Forces layers thinner than the specified value to have a minimum thickness and therefore not pinch-out completely. |
| Reverse Surface Hierarchy | Boolean | Determines whether the surfaces will define layers in a normal (top to bottom) manner or reversed (if on). |
Data To Export
| Property | Type | Description |
|---|---|---|
| Geologic Nodal Data | Multi-select: Layer Thickness, Depth, Elevation | Lets the user decide which data components to generate for the output field on a node by node basis. NOTE: For Structured Grids the Layer Thickness component will be exported as cell data. |
| Geologic Cell Data | Multi-select: Material ID, Geo Layer | Lets the user decide which data components to generate for the output field on a cell by cell basis. |
