ADVectorFunctionDirichletBC
Imposes the essential boundary condition , where components are calculated with functions.
Description
ADVectorFunctionDirichletBC is the extension of FunctionDirichletBC to Lagrange vector variables and is used for imposing so-called "essential" boundary conditions on systems of partial differential equations (PDEs). Such boundary conditions force a particular set of degrees of freedom (DOFs) defined by the boundary parameter to take on controllable values. This class is appropriate to use for PDEs of the form
where is the domain, and is its boundary. In this case, a VectorFunctionDirichletBC object is used to impose the condition (2) on the subset of the boundary denoted by . In this case, is supplied through the Function parameters function_x, function_y, and function_z. If any of those parameters are not supplied by the user, they take a default value of . The user must define one or more sidesets corresponding to the boundary subset .
Note that this BC computes its Jacobian using automatic differentiation
