I have an axisymmetric geometry built from blockMesh, and built a baffle using createBaffleDict. I met an issue when running the createBaffleDict.

Initially, I did not use createBaffleDict, but only built the mesh using blockMesh and then run the solver (pimpleFoam), it runs well and had no issues at all. But, later I added a baffle using createBaffleDict as follows.

internalFacesOnly true;


// Baffles to create.
baffles
{
baffleFaces // group name
{
type searchableSurface;
surface triSurfaceMesh;
name baffle1D.stl;
patchPairs
{
type patch;
patchFields
{
epsilon
{
type zeroGradient;
}
k
{
type zeroGradient;
}
nut
{
type zeroGradient;

}

p
{
type zeroGradient;
}
U
{
type directionMixed;
refValue uniform (0 0 0);
refGradient uniform (0 0 0);
valueFraction uniform (1 0 0 0 0 0);
}
R
{
type zeroGradient;
}
}
}
}
}


I met an issue when I run the createBaffles as follows:

--> FOAM Warning :
From int main(int, char**)
in file createBaffles.C at line 867
Setting field on boundary faces to zero.
You might have to edit these fields.

Removing zero-sized patches:
axis type empty at position 5

Writing mesh to 0.0001

Can anyone provide some help with this issue?
