Hi all,

In CFD-POST, I am trying to get a variable distribution along a constant span curve. I would like to see the variable's variation from the leading edge to the trailing edge, on both pressure and the suction side, which is quite similar to the blade loading chart.

The difference is that now I am not working on a CFX result file directly, but working on an imported surface, a .csv file. Since this is only a surface, there is not enough information to turbo-initialize it and draw the constant span curve directly.

Are there other methods to get this distribution?

Best regards,
Young

Doesn't this mean you will have to write a routine which processes the CSV file yourself? Obviously CFD-Post can only operate on CFX files so it you are processing a CSV file you are on your own.

Glad to have you here, ghorrocks.

I would argue it is not completely on my own.

Since my csv file has the same node coordinate and face connectivity as the original blade, I can export the normalized-span value from the CFX file and add it to csv file. In this way, I can import the csv and make the constant span curve on the imported surface using iso curve.

# the csv file is in form
x y z pressure normalized span
...
face
...

Byt now the problem is the curve lies in the middle of nodes, so there is no pressure value directly stored on it. If I can get the value on that pressure contour, then my problem is solved.

If you put a line through your CFX results on span curve you can then File/Export and generate pressure along the span curve, which you can then externally combine with your existing CSV data. Does this help?
