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.

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.
Cheers, Spencer.

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

Dear All,
I am fairly new to nektar++, and have been trying to simulate the flow in a lid-driven cavity using the adaptive SFD method. However, after the first stability analysis run, I get the following output and error.
Iteration: 1 (residual : 8.559e-27) Writing: "SquareCavityNonuniform110x110-AdaptiveSFD1.fld" L 2 error (variable u) : 1.60644e-14 L inf error (variable u) : 3.59318e-14 L 2 error (variable v) : 1.48736e-14 L inf error (variable v) : 3.72109e-14 L 2 error (variable p) : 1.01877e-14 L inf error (variable p) : 5.76926e-17
Fatal : Level 0 assertion violation Unrecognised value.
I have checked my input files thoroughly, but am unable to understand what this error of "Unrecognised value" mean, or, how it has occurred.
For your convenience/reference, the Geometry/Mesh, the nonlinear problem definition, and the homogeneous linear problem files are attached. Any suggestions/solutions to resolve this issue will be greatly appreciated.
Thank you,
Manish
