<br>
I had a look at your data file and I don't understand where your problem is. I can visualize the X and Y component of velocity and get seemingly correct results (i.e. X and Y have negative and positive values). The magnitude of the velocity vector is as expected everywhere positive.<br>
<br>
Also the Glyph filter produces reasonable results with the default settings (e.g. the arrows can be colored by X or Y component with positive and negative values or by magnitude with only positive values).<br>
<br>
So my question would be: What exactly do you want to visualize?<br>

Hello!<br>
<br>
I tried applying the "Glyph" filter, but still the negative values<br>
aren't being considered. It considers only the magnitude.<br>
<br>
Can somebody please explain in detail how I should go about this? Please<br>
have a look at the .vtk file I have attached above, I am stuck at this<br>
point.<br>
<br>
Thank you<br>

Rohit,<br>
<br>
Assuming that the x-component of VecVelocity has negative values,<br>
then from the selection [Magnitude|x|y|z] pick x and then only<br>
VecVelocity_x will be displayed.<br>
<br>
On the other hand, if "vector plots" are your goal, use PV's Glyph<br>
filter.<br>

Is there no simple feature or option that considers negative<br>
values as well?<br>

Try applying the "Glyph" filter or using the "Surface LIC"<br>
