Study Sequence
A study sequence is a sequence of study steps that a user can choose in the last step of the Model Wizard. Use the Study Sequence node () to define such predefined study sequences. To add a Study Sequence node, right-click Study/Solver Defaults () and select it from the context menu.
Right-click Study Sequence to add the study steps that are part of the sequence. For example, Stationary or Time Dependent. For other study steps, see the COMSOL Multiphysics Reference Manual.
It is only possible to add the study steps that the physics interface supports. If you add a sequence under a physics interface component, all available study steps can be added to the sequence, but it is then not allowed to link to this component from an interface that does not support the study steps in the list.
The Identifiers section is described for the Physics Interface node.
Study Steps for Coupling Features
Under the Study/Solver Defaults node for coupling features, you can add Study Sequence nodes with several study step nodes. For each such study step (Stationary, for example), you can specify, in the Coupling type table, if a physics interface corresponding to a particular coupling type will be solved for or not in the generated study. You can also disable the current coupling feature from the study by clearing it in the Multiphysics couplings table. These tables are found in the Physics Selection section.
Restrictions
Select the Restrict to space dimensions check box and use the buttons under the table to add or edit the list.
Select the User input check box to define the Condition on.
•
For User input in property (the default) enter a Property and a User input. Choose the User input condition: User input is active (the default) or User input has any of certain values.
•
For Expression, enter a Condition as a conditional expression that evaluates to 0 (false) or 1 (true) in the field below.
•
For Feature is active, enter a Feature type.
Select the Condition is not fulfilled for undefined references check box to if you want the condition to be treated as not fulfilled instead of throwing an error if the property is undefined.
If the Study Sequence node is added under a coupling feature, the only option for the Condition on list is Expression. The restriction is then defined by the Condition field and is a conditional expression that must evaluate to 0 or 1 (false or true).
