Normalised x-y-plot
 

Hi! I want to create a x-y-plot of the velocity normalised with the inlet velocity. I wrote a journal using the TUI commands and defined global variables for the inlet velocity components.The problem is there seems to be no command for custom field functions in the TUI and the GUI allows only the input of numbers but not variables. I don't want to change the custom field function again and again because I have to run a couple cases with different inlet velocities. I simply need a plot of V/V_inlet.Can somebody help me? Thanks for your help.
