Unhappy Making a grid from the XY plot

Hello

I am trying to generate a rectangular grid from the XY
plot, but I am having a hard time because the model is
not meshed in a constant distance.

I am making a rectangular grid from a rectangular, but not
flat surface.
There is steady flow on one side of the surface and I am
measuring its wall shear stress.

I have got the plots from the XY plot using the iso-surface
and direction vector. However, the nodes are not in constant
distance so I cannot form a contour map (by using excel and
MATLAB).

Is there any way to extract variables in constant spacing
instead of its cell or node value?

I'm sorry for the long explanation. Please tell me if there
are anything you don't understand.

Thank you very much for your help!

Think Fluent will only display nodal values in XY-plot? Perhaps write values, read them in MatLab and use "interp1"? There is also "interp2" but I don't think this would work in your case; you might have to do "interp1" in one dimension and then in the other.

thank you, jack!

I have been hesitating to use interp1 because the number of plots in the grid were very large and complicated. However, I guess it is the best way.

Thank you for your help!
