I am a new user of FLUENT. I need to know pressure gradient (dp/dx) in a problem. Now in the PLOT menu, there is option to plot derivative. There the notations used are like: dX-velocity/dx mean du/dx (u is the x component of velocity). But i am bit confused about dp-dx, is it directly the pressure gradient or modified by some manipulation? I hope somebody will be able to help out.
