Hi folks,

I am currently working on a supersonic cavity problem. I want to plot p/p_infinity vs. t*V_infinity/D in Fluent for validating my baseline paper.

I have values of p_infinity = 101325 Pa; V_infinity & D with me.

I need help with plotting with these two parameters together.

Plotting the above can be done in Fluent but we'd usually plot a variable againt position using xy plots. You may be better off plotting each variable against position and doing the final plot in Excel or the like.

I will try... thanks.

If that's time, you can monitor "something" over time and do much the same. I find it's generally easier to manipulate data outside of Fluent, simply as I can more easily change units, and add constants to data. 

[se23mcme001]

Yes, that's time only... it should be flow time only, right? remaining two are constants

[Rob]

Yes, flow time only from Fluent. Monitor pressure(?) against time & then into Excel.

thanks, i will try and update
