greetings,

this is my first thread, so im kind of nervous especially because im new to CFD, ok here it goes:

viscous, steady state ,flow over a cylinder, subsonic, (grid generated from icem cfd exported to cfx)

when you do a grid independence study ( from what i read) you need to increase the number of nodes on your grid until your answers dont change, what i dont understand is, wich variable should i choose (velocity presure) and what value of the variable ( max? avarege?), plus my teacher ask us to do a plot of numver of nodes (x axis) vs any variable(y) in order to see the grid dependence clearly, is there a way to do this directly from cfx ? if not how can i export values of a variable to a table on excel or TXT.

thanx in advance for the fast reply, and i apologyze in advance for mi english.
