Disable in Solvers
In some cases a physics interface may declare degrees of freedom that should only be solved for in certain situations. Use the Disable in Solvers () subnode to provide a condition for when a degree of freedom should not be solved for.
To add this subnode, right-click a Dependent Variable Declaration () or Variable Declaration () node and choose Disable in Solvers .
Only one subnode per Dependent Variable Declaration or Variable Declaration node is allowed.
When Disable in Solvers is a subnode to a Variable Declaration node, it is only relevant when that variable is a degree of freedom; that is, when it is defined as a shape function.
Settings
The Settings section has two groups. The first one is enabled by the Disable for study types checkbox, and in it you can specify the study types for which the variable should not be solved. The second group is enabled by the Additional condition for disabling checkbox and makes it possible to provide an extra condition on a user input that also needs to be fulfilled in order for the variable not to be solved for. The settings for the condition work in the same way as the settings under the User input checkbox in the Usage Condition node for components.
