slices animation in cylindrical coordinate

cecilia_xiao559 · January 8, 2015, 14:10

Hello everyone!

I have a CFD result from fluent of part of a generator, which is a cylindrical shape. I want to generate a slices animation but the slices in the cylindrical coordinate instead of the default xyz. Is there anyone know if there is a way to do it?

Thanks a lot!

Hi Cecilia

I am not sure I am following what you are trying to do. Is the data in cylindrical coordinates or Cartesian? If the data is in cylindrical coordinates you can transform them to cartesian using the data alter-> specify equation and use this macro:

$!ALTERDATA
EQUATION = '{CoordinateY} = {CoordinateR} * cos({CoordinateTheta})'
$!ALTERDATA
EQUATION = '{CoordinateZ} = {CoordinateR} * sin({CoordinateTheta})'
$!ALTERDATA
EQUATION = '{MomentumY} = {MomentumR} * cos({CoordinateTheta}) - {MomentumTheta} * sin({CoordinateTheta})'
$!ALTERDATA
EQUATION = '{MomentumZ} = {MomentumR} * sin({CoordinateTheta}) + {MomentumTheta} * cos({CoordinateTheta})'

If you have data in Cartesian to begin with then Tecplot will slice in the x,y,z coordinate system. Do you have an image of the data that might help me understand where the problem lies?

email them to me at d.rittenberg@tecplot.com

Let me know

Hey!

Thank you for your reply. Sorry i wasn't so clear on my first post.

So i have a model in xyz coordinate right now. it is a rotating rotor with a cylindrical shape. I am trying to generate a animation in tecplot with slices in the r/theta plane (looks like the picture i sent you). I want the slices to be rotating about the origin instead of translating through axis (if that makes sense). But right now i can only have slices in the x,y,z plane.
Also, I was able to extract a arbitrary slice from plane and i was shown it was successful. but i can't figure out how to shown them in the "slices" option.n or show the contour/vector etc of that created plane?

also, I am using tecplot 360 2013 R1 version.

Thanks a lot for your help!
