how to draw a pipe(3D) in openfoam?
 

Dear all，

I am a new learner of openfoam. I want to draw a pipe to do some simulation. I have tried my times, but I have not figure it out.

vertices
(
(0 0 0)
(0 0.005 0.005)
(0 0 0.01)
(0 -0.005 0.005)
(0.1 0 0)
(0.1 0.005 0.005)
(0.1 0 0.01)
(0.1 -0.005 0.005)
);
edges
(
arc 0 1 (0.70710678 0.70710678 0)
arc 2 3 (-0.70710678 0.70710678 0)
arc 4 5 (0.70710678 0.70710678 0.1)
arc 6 7 (-0.70710678 0.70710678 0.1)
);
blocks
(
hex (0 1 2 3 4 5 6 7) (200 10 10) simpleGrading (1 1 1)
);
edges
(
);
boundary
(
inlet
{
type wall;
faces
(
(0 1 2 3)
);
}
outlet
{
type wall;
faces
(
(4 5 6 7)

);
}
surface
{
type wall;
faces
(
(0 4 7 3)
(3 7 6 2)
(2 6 5 1)
(1 5 4 0)
);
}
);
mergePatchPairs
(
);
Above is the program that I used to draw a pipe, but it turned out to be a cuboid.
Any idea about this problem?
By the way, I want to make it in openfoam, not in other softwares.

Thank you.

BestRegards,

Bill

Hi Bill,

You are using the blockMesh application which has its own subforum. There is at least one thread which is about 3-D Mesh in a cylinder. Maybe you can find a solution from there.

Dear Mikko,
Thank you for the suggestions.
I will go and have a check.
Thank you.
