Data Structure: Inverse_case |
|
Description |
Defines the data considered for the current inverse case |
Usage |
Inverse_case NUM=ival where ival is the data structure number |
Description |
Overview An optimisation/inverse analysis for a given parameter or set of parameters may require to take into account target results obtained from different experiment setups simultaneously (e.g. the pre-consolidation pressure of a material may be inverted from target results obtained from different triaxial tests at different confining pressures or from a combination of triaxial tests, oedometer tests, etc). Then each experiment setup is considered a different inverse case that is taking into account for the current inverse analysis. Then the Inverse_case data structure is used to identify which of the data defined in the .inp file is associated to a given inverse case. This data comprises: •The File_data structure number (defining the template, target and test folders) •The Misfit_data_set numbers It is also possible to assign weights to the different inverse cases (e.g. we may have more confidence in the results obtained from an oedometer test than the results obtained from a triaxial tests, both taken into account in the present inverse analysis and hence we may decrease the weight of the triaxial test inverse case).

File_data_num keyword is used to define the number of the File_data data structure associated to the present inverse case.

| Case_weight Weight for the inverse case |
Usage |

Description |
||||
Weight assigned to the present inverse case. This is only relevant if multiple inverse cases are taken into account in the present inverse analysis. If not defined the weight for the present inverse case is assumed to be 1.0.
