Data Structure: Util_contig_surface_create |
|
Description |
Creates a contiguous geometry set from a set of non-contiguous surfaces |
Usage |
Util_contig_surface_create NUM=ival where ival is the data structure number |
Description |
Overview Util_contig_surface_create creates a contiguous geometry set from a set of non-contiguous surfaces defined by either geometry set name or stratigraphy horizon name. The function assumes that all faults defining the geometry are defined as geometry sets with name beginning with "Fault". The fault geometry is then used as support surfaces to generate connecting surfaces between the isolated surfaces of the original geometry. The output of the operation is a new geometry set containing both the original surfaces and the newly generating surfaces. |
 | Surface_type Surface type |
Usage |
||||
|
||||
Description |
||||
Surface_type defines the type of surface being considered. Valid surface types are: • "Horizon" - Stratigraphy horizon surfaces for the model • "Side_boundary" - Side boundary surfaces for the model
|
| Geometry_type Surface type |
Usage |
||||
|
||||
Description |
||||
Geometry_type defines the type of surface being considered. Valid geometry types are: • "Initial" - Part geometry surface for generation of initial geometry • "Boundary" - Part geometry surface for boundary condition
|
| Geometry_set Name of the discontinuous geometry set |
Usage |
||||
|
||||
Description |
||||
Name of the discontinuous geometry set. If Geometry_set is not specified then Horizon_name should be specified
|
| Merge_algorithm The type of line merge algorithm to be used |
Usage |
||||
|
||||
Description |
||||
The valid merge algorithm types are: • "None" - No line merge operations • "Complete_line" - Merge is only performed if the complete geometry line is below the minimum width ( Minimum_width) • "General" - (Default) A general line merge algorithm that merges part lines if the length of the merge zone is greater than the minimum merge length ( Minimum_merge_length)
|
| Horizon_name Name of the discontinuous stratigraphy horizon |
Usage |
||||
|
||||
Description |
||||
Name of the discontinuous stratigraphy horizon. If Horizon_name is not specified then Geometry_set should be specified
|
| Output_set_name Name of the output part geometry set |
Usage |
||||
|
||||
Description |
||||
Name of the output geometry set (default: input Geometry_set name)
|
| Output_part_number Number of the output part geometry set |
Usage |
||||
|
||||
Description |
||||
Number of the output part geometry set (default: automatically choose next available number)
|
| Output_file_name Name of the output part geometry file |
Usage |
||||
|
||||
Description |
||||
Name of the output part geometry file
|
| Minimum_width Width of merge zone below which a merge operation is performed |
Usage |
||||
|
||||
Description |
||||
Width of merge zone below which a merge operation is performed (Default 0.25 * average facet length)
|
| Minimum_merge_length Length tolerance for merge evaluation |
Usage |
||||
|
||||
Description |
||||
The minimum length for a merged region and any non-merged region (default 4 * average facet length)
|
| Surfaces List of surfaces to be considered |

Description |

In some cases only part of the geometry set should be processed; e.g. a side boundary may contain multiple units but some units may not be present in the analysis; e.g. they are below the basal horizon. When a list of surfaces are specified only this will be considered. Note that either the Geometry_set or Surface_horizon containing these surfaces must still be specified.

| Part_smoothing_flag Flag indicating that part geometry for boundary displacement should be smoothed |
Usage |
||||
|
||||
Description |
||||
Smoothing of the part geometry used to define boundary displacement is generally required in 3-D to provide a smooth boundary description. This gives more accurate boundary displacement representation in the forward analysis when the nodes of the mesh are only prescribed by normal displacement and may move between adjacent facets. The values of the flag are • 0 - Perform boundary smoothing (default) • 1 - Do not perform boundary smoothing
