Dear Nektar++ developers and users,

I am planing to use 3D flow datas  generated by nek5000.  When I run the command on a centos machine,  the process fails  with errors, as shown below:

While I also tried a 2D case on my laptop, it neither doesn't pass the procession. I wonder if I did the correct things, and thank you in advance!
