[aspect-devel] More vtu problems

[John Naliboff]

Hi Lev,

When you open the paraview view file are you opening the solution.pvd 
file (loads all time steps) or the individual time steps (.pvtu files) 
separately?

If you are opening the solution.pvd file, I would be curious to see if 
the error occurs for the same time steps if you only load the single 
.pvtu file. This would at least help pin-point if this is a "paraview" 
problem, rather than something inherent with the files themselves.

My first guess would have been that you ran out of memory as well, but 
that is clearly not the case. I have had paraview crashes on my laptop 
(16 Gb) with large models and large amounts of output data, but I don't 
remember the exact error messages.

Cheers,
John
