[bye bye my blue]

To watch velocity magnitude, i made plotoverline and plotdata

"Attritube type " includes "Cell Data", "Point Data"

but only "Point Data" can show graph. I don't know what it is.

one more, I run PimpleDyMFoam and the time folder ( it has U, Uf, phi etc..)

I think U is velocity value of Cell data. then What is "Uf"??.

Is "Phi" flux velocity (rho * U) right???


Questions


1. difference "Point Data" and "Cell data"

2. difference "U" and "Uf"


thanks.
