Hello,every one!
I am a newcomer to openfoam and I am solving a pump.It is a pity that I do not know how to set the value of k and epsilon because the units seem not to match the normal units as I know(J for k and % for epsilon). Another problem is the measurement of geometry, that is, how can I know the length of certain line?
I will appreciate it if someone can help me! May you a nice day!
