Sensitivity analysis

Ranks each swept parameter by its impact on surface budget, ECD and breakdown margin. Scenarios are solved with the full depth integration, one factor at a time.

Elasticity is the percent change in the output per percent change in the parameter over its swept span. Share is each parameter's portion of the total swept range for that output. Ranked outputs: Surface budget [psi] · ECD [ppg] · Breakdown margin [psi].
