Data Structure: Fault_relief_set |
|
Description |
To define a fault relief data structure |
Usage |
Fault_relief_set NUM=ival where ival is the data structure number |
Description |
Overview Offset of compressional faults that intersect the surface can result in mesh compatibility issues once the fault offset exceeds approximately 50% of the neighbouring element characteristic length; i.e. as the overhang of the hanging wall relative to the footwall/surface intersection increases. Two methods for representation of fault-relief are available to help maintain a stable solution: •Adding a fillet-radius to the fault/surface intersection to facilitate rollover of the hanging wall onto the model surface •Extending the fault footwall (virtually) to prevent rollover (Not available at present).

 | Active_flag Flag to indicate active status of the data structure |
Usage |

|
||||
Description |
||||
Flag to indicate the active status of the data structure. Valid values are: •-1 - Deactivate and remove if defined • 0 - Not defined • 1 - Defined and active

| Relief_type Type of fault surface relief model during fault offset at the model surface |
Usage |
||||
|
||||
Description |
||||
Defines the type of fault surface relief model during fault offset at the model surface. Valid types are: • "Rollover" - Adding a fillet-radius to the fault/surface intersection to facilitate rollover of the hangingwall onto the model surface.

| Fillet_radius Radius of the fillet between the footwall and model surface |
Usage |

Description |
||||
Radius of the fillet between the footwall and model surface (Default: 2*le where le is the average element characteristic length at the fault tip).
