I don'have the answer for your question but what i can say is that it is not a simple task.

In fluent it should be particularly difficult, if not impossible, because the filter is based on the grid and refining the grid you also modify the filter lenght. The chapter 8 and 9 of Sagaut's book maybe are the right place to start and collect some information about your task.
