[Paraview] Unable to do Volume rendering on BOV file

[Chourasia, Amit]

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
