Hello guys,

I am really new to OPENFOAM. I made a 3-D mesh in Pointwise and exported into the following form as can be seen in the attachment. I just realized that there is no pointZone file in the exported polyMesh and I don't know if that affects the running of icoFoam.

the boundary file looks like the following:

FoamFile
{
version 2.0;
format ascii;
class polyBoundaryMesh;
location "constant/polyMesh";
object boundary;
}

5
(
Buttom
{
type wall;
nFaces 244000;
startFace 72814000;
}
Top
{
type wall;
nFaces 244000;
startFace 73058000;
}
Wall
{
type wall;
nFaces 244000;
startFace 73302000;
}
inlet
{
type patch;
nFaces 20000;
startFace 73546000;
}
outlet
{
type patch;
nFaces 20000;
startFace 73566000;
}
)

and I revised p and U file according to my boundary file as this:

p file:

| ========= | |
| \\ / F ield | OpenFOAM: The Open Source CFD Toolbox |
| \\ / O peration | Version: v2106 |
| \\ / A nd | Website: www.openfoam.com |
| \\/ M anipulation | |
\*---------------------------------------------------------------------------*/
FoamFile
{
version 2.0;
format ascii;
class volScalarField;
object p;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [0 2 -2 0 0 0 0];

internalField uniform 0;

boundaryField
{
Top
{
type zeroGradient;
}

Wall
{
type zeroGradient;
}

Buttom
{
type zeroGradient;
}

inlet
{
type zeroGradient;
}

outlet
{
type fixedValue;
value uniform 0;
}
}


// ************************************************** *********************** //

and the U file looks like this:

FoamFile
{
version 2.0;
format ascii;
class volVectorField;
object U;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [0 1 -1 0 0 0 0];

internalField uniform (0 0 0);

boundaryField
{
inlet
{
type fixedValue;
value uniform (0 -5 0);
}

Wall
{
type fixedValue;
value uniform (0 0 0);
}

Top
{
type zeroGradient;
}

Buttom
{
type fixedValue;
value uniform (0 0 0);
}

outlet
{
type zeroGradient;
}
}


after that, I have created a file called All which include only the command icoFoam. So I expect that when every time I submit the ./All, icoFoam will run.

and it turns out to be this:


// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Create time

Create mesh for time = 0


PISO: Operating solver in PISO mode

Reading transportProperties

Reading field p

Reading field U

Reading/calculating face flux field phi


Starting time loop

Time = 0.005

Courant Number mean: 0.000130326 max: 0.00887154
smoothSolver: Solving for Ux, Initial residual = 0, Final residual = 0, No Iterations 0



after the that the machine exceed maximum time of running and automatically shut the process.

If you have any suggestions or even just some keyword you would like to share with me. Please feel free to contact me. Thank you sooooooo much.

Best,
Tianyang
