Hello Foamers,

May I ask if there is a data structure in OpenFOAM 4.x or higher that allows me to define a volVectorField or volScalarField that is only compromised of integers or longs that I can define in my createFields.H?

I'd like to track an interface with interFoam by determining the neighbor cells that have the interface of an owner cell that also has the interFace.

This means I'd define NeighborField[iCell].x() = CellID_Neighbor_1, NeighborField[iCell].y() = CellID_Neighbor_2, NeighborField[iCell].z() = -1.

P.s. I am using isoAdvector to make my life easier and currently working in 2D.

Also, if anyone has any ideas how to do this in 3D where I can access a owner cell based on owner ID and get its interface Neighbors IDs (predetermined using some code), that'd be great. I don't think a volVectorField would work in 3D.

Kind Regards
vinguva

Hi Foamers,

I thought I'd reply to my own question for future reference for others who may ask this question also.

The data structure to use is:
labelListList for the neighbor cells
List< List<vector> > for the edges of the neighbors.
