Hi All,
I am trying to use SUPG/VMS stabilization for flow problems. In this case,
the velocity as well as pressure are in the same function space e.g linear
quads.
I am setting it us as
FESystem<dim> fe;
fe
(
FE_Q<dim>(1), dim,
FE_Q<dim>(1), 1
);
I now want to set boundary conditions for the solution. Specifically, I have
velocity boundary conditions e.g. inlet, no-slip etc.
I wish to set a fictitious boundary condition for pressure e.g. p=0 at
outlet.
At all other points, I do not constrain p
How do I go about doing this?
We can assume that I have 3 boundary indicators
1 -- inlet
2 -- walls
3 -- pressure zero
Thanks,
Badri
