I'm trying to use fluent meshing to deal with my mesh. But I met the following problem when using fluent3DMeshToFoam. The fluent version is Ansys 2023r1 and I'm sure the .msh file is in ascii format. I can't find any similar error information on google.

Someone said that in the msh file after ansys 2021, the section

(0 "Cortex variables:")

(0 "TGrid variables:")

should be deleted. But that doesn't work.

Can somebody help me?

I also tried to save the file as file.cas.gz and file.msh.gz, and gunzip them. but this error also happens. And it can't be opened with paraview too
