Another LES filtering question

Tim

Hi,

If I would like to explicitly filter a variable in LES then how would I do this?

If I just apply a filter to a F-V cell centred variable I am explicitly filtering an already impicitly filtered variable. Do I have to somehow undo the implicit filter before applying an explicit filter? If so how?

Does anyone know how much the accuracy varies for a case using the same subgrid model but with differing filtering techniques?

Thanks

Tim.
