VectorFunctionDirichletBC
Imposes the essential boundary condition , where components are calculated with functions.
Description
VectorFunctionDirichletBC is a generalization of VectorDirichletBC which imposes possibly temporally- and spatially-dependent values for the Lagrange vector components through MOOSE Function objects on degrees of freedom that fall on the boundary defined by the boundary parameter. That is, for a PDE of the form
where is the domain, and is its boundary. A VectorFunctionDirichletBC object can be used to impose the condition (2) if the function is well-defined for . In this case, the function_x, function_y, and function_z parameters correspond to a set of MOOSE Function objects which represent the mathematical function , and the user must define one or more sidesets corresponding to the boundary subset via the boundary parameter.
