I get error even now. I  modified the way you suggested, but still I get
error. I typed 'visnek lowMach_test'. I get below message in my terminal.

Also one may need to correct for an endian by inserting the first line
"endian big" or "endian little" in case of, e.g., files transfered from
other systems

Total 10 file(s) are in the generated file lowMach_test.nek5000 ... Done!

But when I try to view the files

I get the error again.
