accesing points of a cell in a mesh
 
Dear Foamer,

I hope someone can help me

I have an external solver with a structured grid, I wan to interpolate the values of this grid into a polyMesh .

1) I can create one polyMesh with the information from the structured grid

2) or I can create the polyMesh in a more standard way and just interpolate the values of each grid on each other

I want to create a Chimera Grid like library , I know how to access the Cell center but to have a complete relationship I need to know the coordinates of the cell vertices, more or less like :

forAll(mesh.C(), cellI)
{

forAll(mesh.cells()[cellI].points(), pointI){
Info << mesh.cells()[cellI].points()[pointI].x()<<endl;
}

Info<<mesh.C()[cellI].x()<<endl;
}


How can I write the inner forAll to get the x,y,z coordinates of all points /vertices in one cell ?

Thanks

Did you figure it out? I have the same problem...

Can anyone answer this?
How do you access all of the vertices of a cell?

Code:

mesh.points()[cellI]
only returns the coordinates of a single vertex associated with that cell.
