Re: [Libmesh-users] (Mesh)IO.read_equation_systems ?

[Vijay M <vi...@gm...>]

Roy and John, Thanks for the reply.

I am currently using say VTKIO.write_equation_systems() call to output my
data. I can also use alternately GMVIO and such but I've never tried using
the XDR format before. Are there viewers (Visit, Paraview) that can
understand this format ? 

Also, I do have non lagrangian elements with DG in my computation. Does XDR
class handle this ?

I will modify my output code to use the equation_systems.write() call so
that I produce XDR files. I will let you know later how this works out.
