<br>
I'm using the python interface to run the example "t1.py". I tell it to generate a vtk file. The problem is that when I try to open it with Paraview I get the following error:<br>
<br>
<blockquote><span size="-1">Generic Warning: In /home/buildslave/dashboards/buildbot/paraview-pvbinsdash-linux-shared-release_superbuild/build/superbuild/paraview/src/VTK/IO/Legacy/vtkDataReader.cxx, line 1436</span><br>
<br>

<br>
<span size="-1">vtkUnstructuredGridReader (0x924c360): Unrecognized keyword: ,1</span><br>
</blockquote>
<br>
<br>
Also, if I try to open with the python vtk module I get:<br>
<br>
<blockquote><span size="-1">ERROR: In /work/standalone-x64-build/VTK-source/IO/XMLParser/vtkXMLParser.cxx, line 399</span><br>

<p><br>
This seems strange to me since I'm not changing anything in t1.py except for the output format. Does anybody knows what's the reason of this problem?
<br>
</p>
<p>I would like to point out that at this point I'm just trying to visualize the meshes that I generate, so I would appreciate if you could also let me know of alternative "easy" ways to visualize .msh files.</p>
<p><br>
</p>
<p>Thank you very much.</p>
<p>Best,</p>
<p>David.<br>
