/*! @brief Dirichlet This class is the base class of the hierarchy of Dirichlet-type boundary conditions.
 *
 *     A Dirichlet boundary condition imposes the value of an unknown field on a boundary, which corresponds to:
 *
 *      - imposed velocity for the Navier-Stokes equation
 *      - imposed scalar for a scalar transport equation
