      Hi Manish,

The fix is now in master.

Cheers,
Chris

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

    Subject: Requesting some help with the Adaptive SFD algorithm
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
