how to extract the LES filter delta in creatField.H

hz283 · December 8, 2012, 15:37

Hi All,

I am using rhoPimpleFoam and LES Smagorinsky model. The filter width delta is used in the simulation. Now I would like to use delta() to output another quantity (it is volScalarField type), and I think I can add somes lines in creatFields.H. However, I had some problems about how to use the fileter delta () in createFields.H of rhoPimpleFoam. Delta is calculated in LESModel.H. Does anybody have any experience about this problem? Thank you very much.
