Paraview not reading files previously read

[bjg.hopkins (Ben)]

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

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)

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.

Works fine in ParaView 5.12.0 binary:

I cannot read a .vtp file I could open yesterday. Can someone try to open it?

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.

[bjg.hopkins (Ben)]

Thanks for testing and I’m using Kubuntu 22.04.

Please try with ParaView binary release from https://paraview.org/download

Will do and will report back when done. May be a few days.

OK, all works fine.

Thanks so much.
