Sensitivity

A solver node (

) solves a sensitivity analysis problem set up in The Sensitivity Interface.

Also see The Sensitivity Analysis Algorithm. Sensitivity analysis for time-dependent problems is available with the Optimization Module.

General

In the field, specify the objective to use for the sensitivity analysis.

From the list, choose one of the following options:

•

— The adjoint method solves for the derivatives of a single scalar objective function with respect to any number of sensitivity variables.

•

— The forward sensitivity method solves for the derivatives of all dependent variables and an optional scalar objective function with respect to a small number of sensitivity variables.

•

— This method is a variant of the forward sensitivity method where the right-hand side of the sensitivity problem is computed by numerical differentiation.
