Hello, I’m trying to load in some .vtu files into Paraview that I’ve previously loaded in successfully. They consists of 2D meshes that are the output of Thetis models. [Thetis\_and\_paraview](https://thetisproject.org/outputs_and_visu.html)
They previously loaded in following an action to drag and drop the files in.
This is now causing an error that looks like the one pasted at the bottom of this post.
I have tried to reinstall paraview.
The error references line 20 of the input stream, which is in the attached screenshot
ERROR: In ./VTK/IO/XMLParser/vtkXMLParser.cxx, line 375
vtkXMLDataParser (0x55a7e9bac210): Error parsing XML in stream at line 20, column 0, byte index 892: not well-formed (invalid token)
ERROR: In ./VTK/IO/XML/vtkXMLReader.cxx, line 521

Debug: Off
Modified Time: 295610
Reference Count: 1
Registered Events: (none)
Request: REQUEST\_INFORMATION
ALGORITHM\_AFTER\_FORWARD: 1
FORWARD\_DIRECTION: 0
and so on.
I believe the line causing the issue is line 20 here which looks me to be something of a mess, but, as I say, these files have previously worked in Paraview.
Thanks for your help.

> Hi all, I am trying to open a .vtp file I was able to open yesterday… I am using Arch Linux and Paraview, I just performed the usual system update, no fancy stuff. It is even stranger because I cannot open .vtp files saved from vtk files which instead open correctly. I am attaching the problematic vtp file, error message and Paraview information at the bottom of this message. Thank, I am by no means an expert but this seems a bug to me. Edit: The problem with saving a vtp from a vtk file se…
Which OS are you using ?
@cory.quammen : I think we will need a FAQ for this one if its start hitting Ubuntu.
