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 target results obtained from different experiment setups to be simultaneously taken into account. For example, the pre-consolidation pressure of a material may be inverted from the target results obtained from different triaxial tests at different confining pressures or from a combination of triaxial tests, oedometer tests, etc. Each of these experiment setups is considered a different inverse case and be utilised in the current inverse analysis.
The Inverse_case data structure is used to identify which of the data defined in the ParaGeoInv .inp file is associated with a given inverse case. In the main, this data comprises: •File_data ID number - data structure defining the template, target and test folders. •Misfit_data_set ID numbers - data structures containing history results files for target and model solutions. •Case_weight data which allows for weights to be assigned to the different inverse cases. This can be advantageous when we have a scenario where we may have more confidence in the results obtained from an oedometer test than the results obtained from a triaxial test, both of which are taken into account in the present inverse analysis and hence we may decrease the weight of the triaxial test inverse case.
