How to change airfoil which is not in the list in CPACSCREATOR?
I tried with eclipse and edited x,y,z data. But I'm encountering so many error message from cpacscreator gui.
Please upload instruction to edit code, or upload any tutorial video on that.

Using Eclipse, have you considered the correct arrangement of the profile points? It is described in the documentation as:

Example 1: For a conventional wing, the airfoil coordinates are defined in x and z with all the y-coordinates set to "0". The points have to be ordered from the trailing edge along the lower side to the leading edge and then along the upper side back to the trailing edge.

Examples can be found here:

CPACS/examples/basicWing.xml

NACA2315 is reference file,
And NACA2315 modified is edited file. I replaced the co-ordinates here.

Try to remove a 0 from your y-vector. You 61 x values and 61 z values, but 62 y values.

Mann, Thanks, It worked 💯

And now, Can I add that airfoil separately to the DBtemplate? (Profiles)
If I open new file after adding this airfoil to template, I can choose whatever I want based on presence of airfoil in template.

I mean in this file..

Nice to hear that it is working!

However, I don't really understand your last question. It should of course be possible to add your profile to the template. But I'm not really experienced with CpacsCreator - maybe @aidanjungo, @joergbrech or @rainman110 can help?

[kushaldgowda]

It worked in profile template aslo. :)
