In order to facilitate the creation of fault parameters Fault objects have been created.

Inheritance will be used to minimise the repetition of code. The following inheritance tree will be used:

  • Fault
    • SinglePlaneFault
      • PointSourceFault (Type1)
      • FiniteFault
        • Type2
        • Type3
    • MultiPlaneFault
      • Type4

Each leaf Fault object (The Types) represent a specific type of fault as per our regular definitions.

This allows us to have a uniform representation for a fault.

Currently implemented types are Type1 and Type2.

Types 3 and 4 have a skeleton to be filled later when Pre-processing has nhm generation added to the new workflow.

Type4 faults represent a collection of Type3 faults.

The fault_factory can be used to dynamically retrieve the different types of fault object using the number of the type required.

Type1

Type 1 faults are defined by GCMT parameters

Type2

Type 2 faults are defined by GCMT parameters with a magnitude scaling relation

These scaling relations mean the faults properties can be calculated when the scaling relation for a fault is set.

Additionally it is possible to set a ratio override to force a particular fault shape. Normally this will be set to 1 to force a square fault plane, if used.
