Hi,
ParaView offers you a lot of visualisation and data handling options, so
yes definitely the right choice. :)
Concerning the file format:
The VTK data-structures are well suited for such kind of data, however I
personally find the learning curve of VTK rather steep. Meaning, it
might be quite difficult to get started with this task.
An alternative is to used a HDF5/XDMF file format. I got a simple HDF5
writer rather quickly implemented, there are good tutorials on the web,
and I generate the XDMF file in a post-processing step with a python
script. (ParaView supports XDMF files very well.)
Oh and yes, you can read HDF5 files conveniently with Matlab and Python too.
In any case both options, HDF5/XDMF or VTK, are better than plain
ascii-files. ;)
Regards,
Armin
P.S.: Which language do you write the FEM program in?

Hello Florian,
Yes! Paraview is definitely a good choice. I would also recommend to use
VTK for managing some of the FEM related datastructures. In particular,
I would recommend to use one or more of the grid/cell classes. This also
provides
you automatically with different export formats (see for example the
vtkXMLUnstructuredGridWriter).
Regards,
Marco

Hello,
I want to write my own FEM program. And now I am looking for a
visualization and post-processing tool.
What do you think: is paraview a good choice?
Is there an ascii-fileformat you would recommend to use as output
from the FEM program and as input for paraview?
Thanks,
Florian
