Error from reading vtk files

[hugy888]

Hello,

The vtk file was made using dream3D and we wanted to read it with moose and assign each grain ID from vtk to a subdomain_id from moose.
But when I tried to load vtk file with following code:

[Mesh]
type = FileMesh
file = new.vtk
dim = 3
elem_type = HEX8
[]

Error shows up as followed:

Would you please take a look? Thanks.

Hello

Can you try a FileMeshGenerator instead of the old FileMesh syntax please
https://mooseframework.inl.gov/source/meshgenerators/FileMeshGenerator.html

if that doesnt work i recommend installing meshio and converting it to exodus
