Dear Nektar users,

              I hope you're all doing fine, i'm using the incompressible navier-stokes solver, in fully 3D case with modified basis, and I have a question about the level at which adding curved geometry information, under <CURVED>....</CURVED> xml node, should be done.

Question: is it necessary to add surface curvature information or should one be just fine with adding  curved edges information only?

Regarding this, I have noticed that exporting gmsh higher order mesh produces curved edges and curved faces under <CURVED>....</CURVED> section, which typically reads:
<E ID="45953" EDGEID="26270" NUMPOINTS="3" TYPE="PolyEvenlySpaced">2.54571429e-01 -7.50000000e-03 -6.42857143e-04   2.50785714e-01 -7.50000000e-03 -6.96428571e-04   2.47000000e-01 -7.50000000e-03 -7.50000000e-04   </E>
            <F ID="45954" FACEID="26260" NUMPOINTS="9" TYPE="PolyEvenlySpaced">-1.46714286e-01 7.50000000e-03 3.00000000e-02   -1.50500000e-01 7.50000000e-03 3.00000000e-02   -1.54285714e-01 7.50000000e-03 3.00000000e-02   -1.46714286e-01 1.12500000e-02 3.00000000e-02   -1.50500000e-01 1.12500000e-02 3.00000000e-02   -1.54285714e-01 1.12500000e-02 3.00000000e-02   -1.46714286e-01 1.50000000e-02 3.00000000e-02   -1.50500000e-01 1.50000000e-02 3.00000000e-02   -1.54285714e-01 1.50000000e-02 3.00000000e-02   </F>

Since I'm adding curvature information using an external python script, should I be worried about explicitly adding the face curvature as produced inside an auto-generated session file through NekMesh?
A first naïve thought I had was that the Edges curvature information would propagate the curvature to higher dimensions through the tensor product !? However, I'm not even close to being formal on this statement.

Thank you all in advance,
Kind regards,

Saad
