Hello,

I am trying to convert the DNS data from NEK5000 (.f%5d files such as cyl0.f00001) to NEKTAR++ .fld/chk files using the following command:

FieldConvert cyl0.f00001 cyl_0.fld

The conversion fails with the following error:

Field contains unknown variable: X

Has anyone figured out how to solve this issue ? It would be a great help.I have attached the NEK5000 file for reference.
