I am having a problem reading output from dolfin with paraview... I realise this might not be a problem with dolfin, but a problem with paraview, but there seems to be a compatibility issue: maybe you can suggest a solution? Or I can complain to KitWare...

Here are the symptoms:

Function contains all zeros: will read with Paraview 3.4.0 and Paraview 3.8.0
Function contains small values: will only read with Paraview 3.4.0 - Paraview 3.8.0 complains:

ERROR: In /home/kitware/Dashboard/MyTests/ParaView-3-8/ParaView-3.8/ParaView/VTK/IO/vtkXMLDataReader.cxx, line 508
vtkXMLUnstructuredGridReader (0x2cfa7a0): Cannot read point data array "U" from PointData in piece 0.  The data array in the element may be too short.

vtkXMLUnstructuredGridReader (0x2b7dc50): Cannot read point data array "U" from PointData in piece 0.  The data array in the element may be too short.

e.g. this will generate output which is unreadable:

m=UnitSquare(10,10)
Q=FunctionSpace(m,"CG",1)
R=Function(Q)

pvd2=File("R2.pvd")
small=Constant(1.234e-80)
R.interpolate(small)

pvd2 << R
