Default finiteArea postProcessing probes

Hi Everyone,

Has anyone written anything for post processing / sampling of finiteArea fields?

I basically want to sample along a line of the faMesh but I'm having trouble with locating the correct mesh face to return the values.

It's easy enough to do this for a fvMesh but there are no functions for finding a point within a face of the area mesh as far as I can see. I've tried implementing this myself based on the findCell and pointInCell functions of the primitive mesh but I keep getting errors like the following:

/apps/applications/OpenFOAM/v1712/OpenFOAM-v1712/src/OpenFOAM/lnInclude/GeometricField.H:103: error: invalid use of incomplete type ‘class Foam::edgeMesh’
         typedef typename GeoMesh::BoundaryMesh BoundaryMesh;
I've implemented a find nearest cell function which works fine for a single core but in parallel it obviously searches and finds a cell in each partition which is my issue, hence why need a pointInCell check.

I'm also not sure if the way i'm doing this is necessarily the best way to go about it so if someone with a better understanding of the FA implementation has any insight I'd be grateful.

Thanks in advance,
