Here are some disadvantages of S2S model:

‐ The S2S model assumes that all surfaces are diffuse
‐ The implementation assumes gray radiation
‐ The storage and memory requirements increase as the number of surface faces increases (N x N)
‐ CPU time is independent of the number of clusters used (when Face to Face basis used for view factor calculation)
‐ Cannot be used to model participating radiation problems (absorption, emission, scattering)
‐ Does not support hanging nodes or mesh adaption
‐ Not strictly conservative
