Parameters

p	Index of the patch
s	Side of the patch
t	Type of boundary condition (see condition_type::type)
f	Function defining the boundary condition
unknown	Specifies which unknown variable the boundary condition refers to (to be used if more than one variable is unknown, e.g., velocity and pressure)
parametric	True if the function data for this boundary condition is defined in parametric coordinates.
