The Default Model Inputs node (
) can be added under
Global Definitions to define constant values for model inputs that are used by default for the entire model. Right-click
Global Definitions and choose
Default Model Inputs to display or hide the
Default Model Inputs node. The
Default Model Inputs node also appears if it is hidden when a model input is requested (for example, from a material that is dependent on temperature). If you select the
Group by Type option, the
Default Model Inputs node appears under a
Shared Properties node.
The default model inputs include most physical properties and are always available with a scalar default value. In the settings for the Default Model Inputs node you can change the default values, and you can also override them locally either by a dependent variable (field variable) for the same quantity or by a locally defined
Model Input node (see
Model Input).
Click the Refresh button (
) to update the
Requested Model Inputs section and the
Model input contributions list in the
Browse Model Inputs section to the latest changes in a physics feature, a material, or a coupling feature.
Click the Reset All button (
) to reset all values to their default values.
The Settings window contains the following sections:
Click the Create Model Input button (
) to create a local
Model Input node that you can use to override the global model input in some part of the component geometry.
In this section, you can select a physical quantity (all physical quantities can serve as model inputs) from the General,
Acoustics,
Maxwell,
Solid, and
Transport folders. You can also type in a physical quantity in the text field above the list and click the
Filter button (
) to filter the list of model inputs. If the
Show Only Contributed and Requested Model Inputs button (
) is active, the list of physical quantities only contains such physical quantities that are either contributed or requested model inputs.
When you have selected a model input, its default value is displayed below the list of model inputs under Expression for remaining selection, for example. The default value is a constant value, which can be useful, for example, for evaluating an expression that used a model input before computing a solution. For many model inputs, the default value is 0, but for
Temperature, for example, it is 293.15 K (20 degrees Celsius). You can change that value if you want to use another value for the temperature as a default model input, for example. Click the
Reset to Default button (
) to reset the value it the default value for that model input.
In the table under Model input contributions, the left column contains value of the model input, the
Selection column contains its selection (
Remaining, for example). The icon column contains an icon that represents the interface, or the
Default Model Inputs node itself (
), that contains the provider that contributed a model input. The
Provider column contains the name of the provider of the model input.
Every physical quantities that can act as model inputs declares and defines a common variable that is always available (for example, minput.T for the temperature
T). Any material property that depends on a model input quantity can be evaluated using the common variable.
