The Sensitivity (sens) interface (
), found under the
Mathematics>Optimization and Sensitivity (
) branch when adding a physics interface, provides tools for adding advanced sensitivity evaluation to a stationary model. Basic problems defined only in terms of global scalar objective functions and model parameters can be set up directly in a Sensitivity study step and therefore do not require the use of a Sensitivity interface.
The following nodes are available from the Sensitivity ribbon toolbar (Windows users),
Sensitivity context menu (Mac or Linux users), or by right-clicking to access the context menu (all users).
The main Settings window for the
Sensitivity node contains the following section:
The Label is the default physics interface name.
The Name is used primarily as a scope prefix for variables defined by the physics interface. Refer to such physics interface variables in expressions using the pattern
<name>.<variable_name>. In order to distinguish between variables belonging to different physics interfaces, the
name string must be unique. Only letters, numbers, and underscores (_) are permitted in the
Name field. The first character must be a letter.
The default Name (for the first physics interface in the model) is
sens.
