[Nek5000-users] Curved edges

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

Hi all

I have some questions regarding curved edges in nek.

Is there any way I could create edges in a 3D element that are curved as a
circle?
As far as i can tell the 'c'-option does not allow you to specify the plane
in which the circle should be, and the 's'-option requires your entire
element to be part of a sphere. Are my statements correct?

The 'm'-option is what I have used so far, but the edge is then curved as a
polynomial of degree 2, and I would like to know if it could be
approximated with polynomials of higher degree.

Thanks
Magnus Rud
