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.

Thanks,

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.

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.
