Data Structure: Part_geometry_set |
|
Description |
Geometry part definition data |
Usage |
Part_geometry_set NUM=ival where ival is the data structure number |
Description |
Overview The Part_geometry_set data structure defines a geometry set that does not form part of the simulation domain. Part_geometry_set are used to define boundary conditions e.g. see Prescribed_boundary_data. The part geometry is defined in terms of lines ( Part_line ) in 2-D and surfaces ( Part_surface ) in 3-D. Standard geometry lines ( geometry_line ) and surfaces ( geometry_surface ) cannot be used to define Part_geometry_sets.
Notes •One Part_geometry_set data structure is defined for each part geometry set and several sets may be specified. •When a Part_geometry_set is used to define a Sedimentation_horizon , and the user aims to overwrite the location of the sedimentation horizon at a given stage (e.g. defining a higher elevation than in previous stage) all the data defining the sedimentation horizon will need to be re-specified (e.g. Sedimentation_horizon , Part_geometry_set , Part_surface and Part_nodal_data ).

 | Name Name of part geometry set |
Usage |

|
||||
Description |
||||
Name of part geometry set (Maximum 32 characters)
|
| Part_type Part type ("Standard", "Fault", "Contact", "Discontinuity") |
Usage |
||||
|
||||
Description |
||||
Valid part geometry types are: • "Standard" - Standard part geometry used for prescribed boundaries, etc (Default) • "Fault" - where the part represents a fault geometry, specifically the fault path • "Contact" - where the part represents a rigid, but moveable, contact surface • "Discontinuity" - where a point in 2D or a line in 3D from the part geometry represents a discontinuity (similar to a fault).
Notes •If a change in the part geometry length (e.g. line contraction) is prescribed (via part_nodal_update) for "Fault" and "Discontinuity" types, the deformation will mainly occur nearby the discontinuity point whereas for "Standard" type the deformation will be distributed along the line.

Description |

| Number_fault_divisions Number of sub-divisions for fault offset (default 20) |
Usage |
||||
|
||||
Description |
||||
Defines the default number of divisions for representing fault or discontinuity offset (default 20)
|
| Mesh_generation_only_flag Flag indicating that the part geometry is only required for a mesh generation operation |
Usage |
||||
|
||||
Description |
||||
Part geometry is sometimes required to provide a support (background) surface for mesh generation. Generally, subsequent to mesh generation the part geometry is no longer required. If the Mesh_generation_only_flag is set to 1 the part geometry will be deleted after the next mesh generation step. • 0 - Part geometry is maintained during simulation • 1 - Part geometry deleted subsequent to mesh generation
|
| Time_curve Time curve name or number |
Usage |
||||
|
||||
Description |
||||
Assigns the time curve for prescribed motions of the part geometry surface if it is not used to defined a prescribed boundary load. If a time curve is specified then Part_nodal_update should also be specified to define the prescribed displacement of the part geometry surface. If Time_curve is not specified then the part boundary surface will be static unless it is used to define a prescribed boundary load and the prescribed boundary is assigned a time curve.
|
| Time_curve_number Time curve number |
Usage |
||||
|
||||
Description |
||||
Assigns the time curve for prescribed motions of the part geometry surface if it is not used to defined a prescribed boundary load. If a time curve is specified then Part_nodal_update should also be specified to define the prescribed displacement of the part geometry surface. If Time_curve is not specified then the part boundary surface will be static unless it is used to define a prescribed boundary load and the prescribed boundary is assigned a time curve.

| Output_level Flag for indicating amount of output to the log (.res) file |
Usage |
||||
|
||||
Description |
||||
Flag for indicating amount of output information relative to remesh operations to the log (.res) file. Valid values are: • 0 - Minimum output (default) • 1 - Medium level output • 2 - Maximum level output
