Bad .vtu file written by poisson.jl #179

Open billmclean opened 3 months ago

billmclean commented 3 months ago

I started the first tutorial, running the commands

using Gridap
model = DiscreteModelFromFile("../models/model.json")
writevtk(model,"model")

The files model_*.vtu were written as expected, however when I tried opening model_2.vtu in paraview, I got the following error messages.

ERROR: In vtkXMLParser.cxx, line 364 vtkXMLDataParser (0x55dab2e50fa0): Error parsing XML in stream at line 31, column 1, byte index 2075: not well-formed (invalid token)

ERROR: In vtkXMLReader.cxx, line 576 vtkXMLUnstructuredGridReader (0x55dab2c58f20): Error parsing input file. ReadXMLInformation aborting.

My Julia versioninfo() output is

Hi, @billmclean, this looks a lot like this issue https://github.com/JuliaVTK/WriteVTK.jl/issues/136

Therein, they suggest some workarounds.

Hope this helps!
