hi,

i have a big problem when i try to use the function buoyantSimpleFoam.
OpenFoam brings me always this error message:

almir@ubuntu:~/OpenFOAM/Netz/mittel$ buoyantSimpleFoam

I dont understand that, when i go into the constant-folder there is no file called "g".
In my case i have about 300 patches, maybe the high number of patches is the problem. I have unit some of the patches in the boundary conditions (in the 0-folder) with the function
boundaryField
{

"patch[1-358]+"
{
type fixedValue;
value uniform 303.75; // 30.6 degC
}
maybe this is the problem??

but i also have made a simple example with an easy geometry with only 9 patches and i get same error message.

can somebody help me?

The error message is telling you that the g file does not exist. Try putting it in the constant directory.

hi Andreas,

thank you! you have solved my problem.

hi,

now OpenFoam brings me a new ErrorMessage:

I think my problem is that i have used for meshing Netgen 4.9.13. this was working quite good, and also the export to OpenFoam Format. But in the constant-folder my boundary-file is looking like that:

9
(
patch1
{
type patch;
physicalType patch;
nFaces 126;
startFace 7486;
}
patch2
{
type patch;
physicalType patch;
nFaces 132;
startFace 7612;
}

and i wont to use the tutorial-files from buoyantCavity for my research, and i have edited them with the patches i have from Netgen. For example i have edited alphat-file like that:

FoamFile
{
version 2.0;
format ascii;
class volScalarField;
location "0";
object alphat;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

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

internalField uniform 0;

boundaryField
{
"patch[4-9]+"
{
type alphatWallFunction;
Prt 0.85;
value uniform 0;
}

"patch[1-3]+"
{
type alphatWallFunction;
Prt 0.85;
value uniform 0;
}
}



So my question is how i have to edit the files in the 0-folder (alphat, epsilon, k, mut...)? Or do i have to edit the boundary-file?
