[Paraview] Distortion when loading time varying vector field from raw binary files using xdmf reader

[Tobias Benz]

Hi,

I have a time-varying 2D vector field (2D velocities) of the size 256 by 
256 pixels sampled at 294 points in time. Each frame is stored in a raw 
binary file ('uv_0000.raw' to 'uv_0293.raw'). I am using 
'timeseries.xdmf' [1] to load this data into ParaView.

Unfortunately, in ParaView 3.98.0  on both Linux64 [2] and Windows64 
[3], the vector field is displayed heavily distorted.

Am I doing something wrong or is this a bug?

Any advice would be greatly appreciated!

Tobias
