Problem manipulating Data in Tecplot after foamToTecplot Conversion

titio · June 4, 2008, 13:58

Hi Guys,

I am starting to use openFoam, and as a test I am studing the flow in a sudden expansion, in 2D. To the post-processing, I use the foamToTecplot to convert the results and to treat them in Tecplot. I can convert the data, represent the results using contours.

But, when I try to create some stream lines, I got the error "Data is FE Brick or Tetrahedron. It is best to use 3D". I can do some stream lines in 3D, but it is awkward.

Thanks,

António Martins

Data>Extract>slice from plane

Although 2D, openfoam extrudes it in z. so slice a plane at constant z.

Go to zone style and activate the newly formed slice
and deactivate the original 3d.
view the result as 2D cartesian.

Thanks for that info. In the case of a transient solution you need to select 'extract slices over time' - which will give you the same option for each time-step.
