Prescribed Solution

The domain condition (found under the submenu) lets you specify the value of u on a set of domains. It is thus a Dirichlet condition applied at domain level that overrides the equation for u that would otherwise apply.

Prescribed Solution

The prescribed solution for each dependent variable (for example, u2), has a corresponding check box (), which is selected by default. Enter a value or expression for the prescribed value in the associated text field or clear the check box as needed. If cleared, no Dirichlet constraint is added for that dependent variable on the selected domains.

Constraint Settings

To display this section, click the button (

) and select in the dialog box. This section contains settings for specifying the type of constraint and whether to use a pointwise or weak constraint. See Constraint Settings for more information.


	You can add subnodes to exclude the constraint from any surrounding boundary, edge, or point. See Excluded Points, Excluded Edges, Excluded Surfaces.


	See Coefficient Form PDE for all the settings and Compact and Standard Notations for Classical PDEs for the equations that the Classical PDE interface solves.
