No errors.


Here's the entire .pvd file:

I don't know why it has entries for more than 1 time step, since the 
righthand side of the timesteps window (which I opened just to check) 
only listed the single input file.  I was running a 4-process parallel 
paraview, not 10-process, btw.

Here's the XML header of one of the .vtp files to which the .pvd file 
points.  I have no idea where the name, "Scalars_", that was assigned to 
the scalars, comes from:
