Pressure boundary conditions

Pressure boundary conditions

Ver: 0

DESCRIPTION

For flows through porous media, boundary conditions must be specified for the generalized Laplace equation in terms of Dirichlet (prescibed pressure) or Neumann (prescribed normal velocity) conditions. The user is allowed to modify the boundary condition for each boundary set.

By default, a zero pressure is prescribed on the boundary of the flow domain (including interfaces).

The title of each entry contains the current type of pressure boundary condition and the corresponding boundary set number.
