[dune-pdelab] Reg: terminal freezes at vtk output

[Shubhangi Gupta]

Dear all,

I am currently experiencing a really strange problem during the 
execution of my dune program... When I run the problem in parallel, the 
program execution freezes in the terminal just before writing the vtk 
output file... the freeze occurs randomly, sometimes right before the 
first output, but sometimes after 5, 20, or even 500 outputs, even 
though I don't change anything about my problem setting! I am really 
puzzled, and I'll be very thankful for suggestions for solving/debugging 
this!

Thanks in advance, and best wishes, Shubhangi

PS: So far, this problem occurs only in parallel. I write vtk output as 
follows:

         int subsampling = 0;         typedef 
Dune::SubsamplingVTKWriter<GV> VTKWRITER;         VTKWRITER 
vtkwriter(gv,subsampling,(int)0);         typedef 
Dune::VTKSequenceWriter<GV> VTKSEQUENCEWRITER;         VTKSEQUENCEWRITER 
vtkSequenceWriter(    std::make_shared< VTKWRITER (vtkwriter), fileName, 
pathName,""    );         .....         .....         
vtkSequenceWriter.write(time,Dune::VTK::appendedraw);
