frontiere_ouverte_gradient_pression_impose

Inherits from: neumann

Normal imposed pressure gradient condition on the open boundary called bord (edge). This boundary condition may be only used in VDF discretization. The imposed $\partial P/\partial n$ value is expressed in Pa.m-1.

Parameters:

ch (type: front_field_base) Boundary field type.

frontiere_ouverte_gradient_pression_impose_vefprep1b

Inherits from: frontiere_ouverte_gradient_pression_impose

Keyword for an outlet boundary condition in VEF P1B/P1NC on the gradient of the pressure.

Parameters:

ch (type: front_field_base) Boundary field type.
