Since values of k and epsilon
 
Since values of k and epsilon in turbulence model are dependent on the velocity. So I want to use a new boundary condition for varying k and epsilon. Was this already implemented or not?

At the moment I wrote a boundary condition for the k based on the "timeVaryingUniformFixedValue", it is running, but in the source code I don't need to use timeDataFileName for reading some parameters from the data file, so how can I remove this part properly, or can you even recommend me another existed boundary condition as template? Thanks!

Thank you so much! That is exactly what I need. Plus, the mass-flux boundary condition is something I'm really interested in. http://www.cfd-online.com/OpenFOAM_D...part/happy.gif
