[Paraview] Volume Render Plot - Unreasonable results with vector components or magnitude

[Dietzel Mathias]

Hello everyone,

I am using Paraview's Volume Render plot to visualize a velocity field inside some technical equipment. In case of plotting a component of the vector field or the magnitude of the vector (both from the drop-down menu) with volume render I get unreasonable results, e.g. minimum or maximum zones are not shown correctly or the flow direction seems wrong. However, if I calculate a scalar value from the vector that corresponds to the component or to the magnitude (e.g. using the calculator filter in Paraview) and then plot by volume render, the fluid field is represented correctly.

The data itself seems OK since a surface or slice plot leads to the same (correct) results, no matter  whether I use the vector component directly or the scalar value. I tested the behavior with several data sets. I am using Paraview 4.3.1 64-bit and Paraview 5.1.2 64-bit - both show the same behavior.

I appreciate any comment.

Best regards
Mathias Dietzel
