Normal velocity imposed along boundary

Ver: 0   DESCRIPTION For problems of flows through porous media, entering this menu allows the user to specify natural boundary conditions for the momentum equation (Darcy's law). The default value for the normal velocity is zero. A non-vanishing value can be selected. A vanishing normal velocity is equivalent to selecting a no-slip boundary condition.   OPTIONS

Upper level menu
1
Constant
The normal velocity is constant on the corresponding boundary line or face
2
Linear function of coordinates
A linear dependence upon the current space coordinates can be selected
