Hi Amit,
Is your mesh uniformly spaced?
If I'm not mistaken, PV does not currently support native volume
rendering of stretched Cartesian meshes (ie vtkRectilinearGrid). However
it does support volume rendering on uniform Carteisan meshes and other
data types. There are quick and dirty ways to convert the stretched
Cartesian meshes to a data type for which volume rendering is supported
in the GUI. Obviously not ideal, but would let you render something quickly.
The default BOV reader in PV is the VisIt BOV reader which always
generates a stretched Cartesian meshes even when the data is uniformly
spaced. This is a VisIt issue. If you have uniform spacing then you
should use a different reader. On the other hand if you really do have a
stretched Cartesian grid then the quickest path to a volume rendering is
to convert to an unstructured grid. You can do this in the GUI after you
open the data apply a threshold filter (set the threshold so that all
data is passed, the defaults should do it).

Hi Amit,
XDMF data format is a little better than BOV in ParaView for rectilinear
data. VisIt will also read XDMF.
An example code can be found here:
https://raw.github.com/openmichigan/PSNM/master/KleinGordon/Programs/KleinGordon3dMpiFFT/xdmfcreate.f90
The corresponding example program to create BOV header files is here:
https://raw.github.com/openmichigan/PSNM/master/KleinGordon/Programs/KleinGordon3dMpiFFT/bovcreate.f90
These programs take as input the number of grid points in each dimension
Regards,
Benson

Hello,
I am loading a BOV file into Paraview, however I do not get an option for
volume representation.
Do I need to add something else to the bov header file other than standard BOV
specifications?
Alternatively is there a better way to load a rectilinear uniform grid data
into paraview other than using BOV header files.
Help appreciated.
Cheers

Amit,
Do you have sample dataset to share? Feel free to share it of the list if
needed.
