velocity vector on 2d plane not 3d

akbar.mech · December 29, 2016, 05:12

hi
I am simulation swirling flow in fluent. when i want to see the velocity vectors in fluent, i define a plane and in the vectors menu, i choose that plane to show the vectors on that and from the vector options select the "in plane" button to show the vectors inside the plane i have defined.
now my question is:
how can i do the same in tecplot? because when exporting data to tecplot there is no "in plane" option.
any help is appreciated

any idea ?!!!!

It's difficult for me to see exactly what you want. But let me know if this helps,
(1) create a slice in your 3D geometry. Define the position and plane normal.
(2) then Data>extract> Current Slice (NOTE: this is not available in certain versions of tecplot)
(3) Change the plot type to 2D Cartesian
(4) Figure out how to plot the vectors here

=============================
I have the same problem. Actually, I am simulating a flow which is rotational in (or say ) helical in a tube. Its sort of rotational periodic segment. I want to see velocity vectors in a 2dplane, that I made in Fluent but it does not show rotational flow in vector plots/ Now I want this in TEcplot. And there too it does not show vectors rotating. Where I am doing wrong?

Fluent inputs
========
mas flow inlet
x,y and z direction = 0 0 1 (Cartesian X, y and z)
Rotation about z axis
Flow is rotational periodic about z axis.

Tecplot
=====
Do I need to change vector from u v w velocities corresponding to x, y and z directions?

It's difficult to say exactly why your vectors aren't plotting for correctly. make sure that the correct variables are assigned to the correct velocity/cartesian components would be a good start

Actually I did this, but the problem is not solved. Do I have to use some equation(s) , some conversion for velocity components or so?

hello dear

I want to plot velocity vector for a 2d case in CFD- post but I received an error as:

" variable velocity is not a variable vector."

I export velocity vector as variable from Ansys fluent.

can anyone help me?
