changing LES models problem

maysmech · August 27, 2010, 02:35

Dear Foamers,

Using pisoFoam LES and changing oneEqEddy to dynOneEqEddy leads to "need dynOneEqEddy coeff" error when typing pisoFoam in terminal.

What changes should be considered when changing LES models?

Where can we find needed revisions?

Did you try finding the LES properties file from the directory where you took the dynOneEddy? Try searching for a tutorial which uses the dyn.. on doxygen OpenFoam

You should also change some /0 coefficients. For instance, wall functions change according to which model (dynamic or not) you use.

As Rickard said, try to find a tutorial case and adapt it to your study.
