Does DIAdem support polar 3d contour plots, i.e. f(r, phi) instead of f(x,y)

Solved!
Go to solution

Hello

I need to plot a flow velocity profile across a circular tube. Coordinates will therefore be not in x,y (easy job for DIAdem, I know) but in r and phi.

I could convert the radius and angle information to x and y coordinates, but then they will not be evenly spaced and the axes will not reflect the set-up.

 

Any idea?

 

Thank you

Michael

Hi Michael

 

No, DIAdem does not support r, phi in 3D plots. But you can find an example in DIAdem which shows you how to display this in DIAdem. To find the example start the ExampleFinder, open new examples for version 10.0 and then select the example "ASCII File Loading and 3D Display". You will find most of the functions that you will need for your question.

 

Hope this helps

Hi Winfried, 

Is there any news related to the subject of this topic in the new release of the software? 

I need to generate a lot of contour ploar plots as well, It would be a pity that Diadem is not capable to do that (Angle, Radius position, and color for the value of the variable). 

 

Thanks

Hi michebel

 

DIAdem does not support 3D contour plots in DIAdem 2018. You still need to calculate x and y from angle and radius to use it in a 3D plot. Feel free to add this request to the DIAdem Idea Exchange.

Hi Winfried  Michebel

Maybe this entry in the idea exchangewill give us what we are looking for. And maybe worth a kudo.

not exactly, 

what I'm looking for is contour polar plot like the one attached, that it's a 3D polar plot. To be honest I think it's a very basic plot, quite strange is not possible to get it without using walkaround like the one suggested above.

You are right. And also, as pointed out in my 2010 original post, the algorithm to interpolate gives quite different results when you interpolate from [r, phi] coordinates instead of from [x(r, phi), y(r, phi)] coordinates.
