Hi Ajeesh, The executable for FieldConvert could be found in your local nektar directory, for instance: ~/Ajeesh_PhD/codes/Nektar++/nektar++/build/dist/bin/FieldConvert It should be there if you compiled with make install If you wish to run FieldConvert (or any other executables) on your terminal directly you will need to add the directory above into your PATH variable, for instance export PATH="~/Ajeesh_PhD/codes/Nektar++/nektar++/build/dist/bin/:$PATH" Hope this helps! Cheers, Chi Hin ________________________________ From: nektar-users-bounces@imperial.ac.uk <nektar-users-bounces@imperial.ac.uk> on behalf of Ajeesh Mohan T <tajeeshmohan@gmail.com> Sent: 13 February 2024 06:56 To: nektar-users <nektar-users@imperial.ac.uk> Subject: [Nektar-users] FieldConvert: command not found This email from tajeeshmohan@gmail.com originates from outside Imperial.

Hi nektar-users, I am new to Nektar++ and just installed it in my Ubuntu 22.04 by compiling from the source obtained from GitHub as instructed in the user guide. The installation was successful without any errors and I tested it using ctest command where all of the 760 test cases passed successfully (screenshot is attached). My primary objective is to obtain tecplot readable formats from some Nek5000 outputs I already have; using the FieldConvert utility (It also supports the reading of data files from Nek5000 as claimed in the user guide). However, the problem I am encountering is that the terminal does not recognize the FieldConvert command. I am not able to find the issue anywhere on the internet. It will be very helpful if any of you can help me with this. Thank you in advance. Warm regards, Ajeesh Mohan T, Doctoral Research Scholar, IIT Bombay, Mumbai, India. [Nektar++_test.png]
