How to read fiber data from .vtk files using meshtool

Question

Hello,

I was attempting to load a mesh model from this resource found here. From the description, I am expecting to see fiber orientation data in the .vtk files. However, meshtool cannot find the fiber data when converting.

Upon text inspection of the .vtk files I can see that a section with "VECTORS fibres float" exists, so it seems that the fiber data is present but cannot be read.

Here is a sample call to meshtool that I used:

    meshtool convert -imsh input_mesh_basename -ifmt vtk -omsh output_mesh_basename -ofmt carp_txt

I have tried comparing the problematic file to other .vtk files I have. One difference I can see so far is that "fibres" were changed to spelled "fibers" in recent meshtool versions, though I don't know if this matters.

Should I try using an older version of meshtool? I have gone back as far as 2021 but no success so far.

Hi!

I just fixed the bug in meshtool, that caused the fibers to not be found. If you update your meshtool version, the conversion should work.
