X,Y plot

Jiang · August 16, 2012, 05:06

I'm trying to plot a X,Y line with Cp against theta of a cylinder, but im not sure how to approach it. im new to tecplot. any help would be nice, ty

Open a new file, say "XY.dat", and fill it with your data, two numbers per line, i.e.,
theta1 cp1
theta2 cp2
...
thetaN cpN
Save the file and then open it with TECPLOT.

This would work, yes thank you
But i have the case and data file from fluent. Which is loaded into TECPLOT, cant i use arbitrary Radius, Radius = X*X + Y*Y + Z*Z and then extract a iso-surface i want. then change the X varible in the XY plot to angle, theta of the cylinder?

hi
how to plot average velocity vs direction vector in fluent?

i guess it is not conveninent to extract an iso-surface in tecplot, but you can get one in fluent easily. when you get the geometry surface in fluent, you can export the physical data(e.g. cp) with correspoding geometry position(e.g. x,y,z or r,theta,z) into an tecplot file. After this, you can load the tecplot file into tecplot and plot the cp vs theta curve

Hi
Dear members of CFD-Online, I have a simple question:
What does 'Position' mean in sphere's xy-plot??
Thanks
