Hi everyone!

I would be grateful if someone can explain me how to use perturbU.
I checked on forum other's posts but I still don't know how to use it.

How can I add perturbation on interface between two fluids?
For now I just wmake it (perturbU for channel) and I added in transportProperties Ubar. That's all I do for now. Is there something other I must set before I can use perturbU?
Because after i try to use it i get this error:

From function regIOobject::readStream()
in file db/regIOobject/regIOobjectRead.C at line 73.

FOAM exiting


I am sorry on asking such question, but I am new to all this and I would really need some help.

Thank you...

Ok, I figured it out how to use it. It's working.

Can somebody explain me what are and how can values in perturbUDict file be set up properly:
duPlus, betaplus alphaPlus, sigma, epsilon...?
