The Periodic Condition node adds a
periodic boundary condition. This periodicity can be continuous (the default) so that
u(x0) = u(x1) or antiperiodic so that
u(x0) = −u(x1) and can control to which dependent variables the periodic condition applies.
Select a Type of periodicity:
Continuity (the default) to make the dependent variables equal, or
Antiperiodicity to make them antiperiodic:
u(x0) = −u(x1).
For each dependent variable in the PDE, choose to apply the periodic condition by selecting, for example, the Apply condition on variable u1 check box. By default, the periodic condition applies to all dependent variables.
