Hello,

I’m using ParaView 5.11 version in Windows 10, Ubuntu 16, and MacOS 10.15. And I met an error and a solution. I attached my data and shared how to reproduce.

1. Load export01.pvd (wind data)
2. Calculator : Define velocity = u \* iHat + v \* jHat + w \* jKat
3. Representation : velocity, Stream lines
4. In Steam Lines panel : Vectors : velocity, Step Length : 5
5. Open dem.pvd (terrain data)
6. Representation : “Band1”, surface

Now we can find that the stream lines disappeared by terrain color.

But, I found a solution:  
7. Delete Calculator1.  
8. Repeat step 2-4.

From now on, the animated stream lines have been overlapped with terrain data.  
This must be an error.

I hope my steps would be reproduced.  
Thank you.
