export to Paraview own solver
What format should i use to export to Paraview? I am developing my own solver and i am looking for the best format to use. Paraview has native VTK files, but i could also use Ensight or others. What would be the best choice?

Re: export to Paraview own solver
In my opinion, Ensight's format is the easiest to understand, implement and use (even for parallel post-processing). I've put some ParaView stuffs, including the Fortran routines I use to export Ensight's file, available in

Re: export to Paraview own solver
Where can we find the details of Ensights format, could you provide some links. My solver exports in fieldview, i wish to add more exports to it.

Re: export to Paraview own solver
I included the Ensight's format description in the file. Take a look ;o)

Re: export to Paraview own solver
Hi Renato,

I would like to export elmer data to VTK format so that I can use paraview to view the results. I have no idea of VTK format. Do you have any fortran code to show how to export data to VTK format? Thanks!

Re: export to Paraview own solver
Any ideas why this is not working?, the ascii version is working fine, but when i try binary its crashing paraview.

Hi Renato,

I compiled and ran your testprogram 'fortran_ensight_test' using CVF on Windows XP. But paraview crashes reading the binary files. I tried all available numeric formats for unformatted data (compiler option). But it won't help.

What compiler/system combination did you use?



Bart Paarhuis January 17, 2013 16:12

After a lot of trial and error, I finally got the ensight binary files to work with the CVF compiler: :):):)
- open(...,form='binary',convert='BIG_ENDIAN') for the geometry and result files instead of open(...,form='unformatted')
- and using 'C Binary' instead of 'Fortran Binary' as the first line in the geometry file
