[Nek5000-users] Corner elements giving large values

[nek5000-users at lists.mcs.anl.gov]

Dear Nek forum,

      I am simulating Rayleigh Benard flow in a 3D finite cylindrical annulus.
      I am getting spurious large values of velocity at the corner regions
      of the annulus i.e. the edges where the inner cylinder joins the
top and bottom
      planes. The boundary condition is no-slip and no penetration for velocity
      at these edges. Can someone point out a plausible reason.

Thank you
Swarandeep
