I' m new in OpenFOAM 2.10. Recently I finished the case "floatingObject" with the solver interDyMFoam.

what does sigma mean in the file transportProperties? I use kEpsilon model, and the case use default paramaters.

at the same time, if i want to choose stardard kEpsilon model, how to assign related paramaters.
Thank your for help.

the sigma is the stefan-boltzman constant.
it is declared in /opt/openfoam211/src/OPENFOAM/global/constants/physicoChemical
you can look for it.

the bolzmann Constant has to be corrected by surfaceTension/bolztmannConstant...

Sorry I could not resist.
