A kind of average maybe (in case of polyhedral mesh). Idea is that i have negative Heat Source (written currently as a equation on a paper) that sets Heat Source according to difference between current Cell's Temperature and next to that neighbour's in x-direction Temperature; so that would be Code: grad($Temperature)[0] that should be multiplied by Δx. In fluent that was possible due to damned C-code loop; in Star-CCM+ ... ?
