generating 2d-planar contour plots from a contour plot on a curved surface
Hi fellas,

I have a problem with CFX post.
I have a turbine blade and I have solved the flow around it numerically.
I can see the distribution of any kind of variable that I like on the curved surfaces of the blade using the contour plot option in CFX post.
Now I would like to project this contour plot values onto a planar surface but I cannot do it.
In other words I am looking for some methods to make the contour plot on the curve surface planar.
Any ideas?
Any kind of help is much appreciated.

I would export the data from CFD-Post and do this in a more advanced post processor like tecplot, fieldview or ensight. If you don't have those you can do the plotting yourself in python if you are handy at maths and programming.

I have spent time playing with these softwares that you have named but to no avail.
has anyone previously done this successfully?

If I was going to do it I would do it in python. You would have to write a routine which reads the imported file, transforms the coordinates to a 2D plane and then plots it. If the transform is simple this is only an hour or two's work. If the transform is complex this could take a few days work.

Have a look at python, numpy and matplotlib.
