To whom it may concern  
I have a problem with Paraview. I did a simulation with Elmer and exported it to Paraview. In Paraview, In velocity distribution, it seems that the empty tube inside the geometry velocity is zero but, I expect that velocity inside the empty tube is higher than the bottom and top of the tube. I think that maybe modeling doesn’t work well In the tube part. I would be pleased if you kindly help me with this issue.
