Hi Spencer, Thanks for your response. Please find the attached the nek5000 file, along with the *xml file containing the same grid, in case it's needed. regards, Wei On Sun, Nov 3, 2024 at 11:15 PM Sherwin, Spencer J <s.sherwin@imperial.ac.uk> wrote:

HI Wei,

Not sure if anyone has gotten back to you. I was not aware we had a converter from nek500 field files but can see one has been added. Anyway if you post a input file we can see if it also fails for us locally.

Best,

Spencer.

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!

Wei
