Extracting sub surface stress

Hello Simulia Community,

I am working on a contact simulation wherein I am interested in extracting the sub-surface stresses. I could have before running the simulation, created a layer or two of the mesh at a certain depth below the surface and it then would have been easier to get the stresses. But right now, from the .odb is there a way to extract subsurface stress at a given depth by means of extrapolating the known stress values?
