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
