Pressure boundary condition along boundary i

Pressure boundary condition along boundary i

Ver: 0 DESCRIPTION For flows through porous media, allows the user to specify or modify the type and parameters of the pressure boundary conditions imposed on boundary set i. The current setting is recalled in the header.

Selecting an option sets the type of boundary condition. Polydata will then prompt the user for the parameters associated with the boundary condition in use.

OPTIONS

-1
Upper level menu

The current pressure boundary conditions are accepted on boundary set i.

0
Interface

Interface pressure boundary condition is available for multi-layer Darcy flow problems. It requires continuity of the pressure field, together with continuity of the interfacial normal velocity. For Darcy flow problems, interfaces are fixed. Interface conditions are available along intersections of sub-domains only.
Interface conditions in domain A along domain B also require interface conditions in domain B along domain A.
In case of incompatibility, an error will be reported at thelevel of the task.

1
Pressure imposed

Default : pressure = 0.

2
Normal velocity imposed

Default : normal velocity = 0.

3
Wall

A vanishing normal velocity is imposed.
