+## Getting interface centers (for droplet height) and interface normals (contact angles), isInterfaceCell information for identifying interface cells
+
+1. reconstructionSchemes class contains volVectorFields for normals and centers, ([see reconstructionSchemes.C constructor](https://www.openfoam.com/documentation/guides/latest/api/reconstructionSchemes_8C_source.html)
+
+The fields are named "recon::normal", "recon::centre", and are _registered to the mesh_ , which means, we can use the FO, to query the mesh for these fields
+
+const volVectorField normals = mesh.lookup<const volVectorField&>("recon::normal");
+const volVectorField centers = mesh.lookup<const volVectorField&>("recon::normal");
