Make sure you have installed last version of ParaView. 'LBMflow.pvd' file can be opened directly in ParaView.

 

Open LBMflow.pvd in ParaView

 

Do not forget to 'Apply' the changes to load the first file.

Now selecting the next step you can load next time-step file and analyse your results:

 

 

Single Phase simulations contain only velocity field and to visualise it you need to use 'Glyph' function:
