Hi Manish, Thank you for reporting this. I think I found a bug which might be causing this error. I will fix it and hopefully the fix will be in nektar++ master branch soon. Cheers, Douglas 2016-04-12 19:50 GMT+01:00 Sharma, Manish (sharmamh) <sharmamh@mail.uc.edu>:

Hi Douglas, Thank you very much for your prompt response. May I request you to let me know when this bug is fixed, and when the fix is included in the nektar++ master branch? In addition, can you please also let me know how I can include this fix from nektar++ master branch on to my system?

Hi Manish, Do you know how to compile Nektar++ from a branch? When Douglas has implemented the fix there will be the possibility to download the branch to test before it makes it into Master.

Hi Chris, and Douglas. Thank you very much for fixing this bug in the code. It is working fine now. Dr. Sherwin, I had downloaded and compiled the code from the master section of the Gitlab, and it worked just fine. Is this what you meant by "Do you know how to compile Nektar++ from a branch?"? Thank you all for your help. I greatly appreciate it.
