How to define the geometry of an inlet?
Hi all,
I am trying to simulate flow through that passes through a sluice gate and into a flume. I have been trying to represent the flow from the sluice gate as an inlet patch that is part of a face while a wall composes the rest of that face. In doing so I get the following error:
Code:
FOAM FATAL ERROR:
face 0 in patch 0 does not have neighbour cell face: 4(0 8 9 1)
Here is the rest of my geometry:
Code:
vertices
( //Domain
(0 0 0) //0
(0 0 0.31) //1
(20 0 0.31) //2
(20 0 0) //3
(0 0.45 0) //4
(0 0.45 0.31) //5
(20 0.45 0.31) //6
(20 0.45 0) //7
//Inlet
(0 0.02551 0) //8
(0 0.02551 0.31)//9
);
blocks
(
hex (0 1 2 3 4 5 6 7) (25 25 15) simpleGrading (1 1 1)
);
edges
(
);
boundary
(
inlet
{
type patch;
faces
(
(0 8 9 1)
);
}
walls
{
type wall;
faces
(
(0 3 7 4) //sidewall
(1 2 6 5) //sidewall
(0 1 2 3) //floor of channel
(8 4 5 9) //above inlet
);
}
outlet
{
type patch;
faces
(
(2 6 7 3)
);
}
atmosphere
{
type patch;
faces
(
(0 3 7 4)
(8 4 5 9)
(1 5 6 2)
(1 3 2 0)
);
}
);
I understand why I am getting this error, but now I'm wondering how can I represent the flow from the sluice gate so that the flow depth from the inlet is constant? |
