Re: [Nek5000-users] Compute the derivatives

That's ok! The SEM solution is by construction in C0 but not in C1. Note: The jump in the derivative vanishes if N -> infty. If you want to force the derivative to be in C0 just use dssum(). Hth, Stefan On Jun 8, 2010, at 2:30 PM, [email protected] wrote:

Hi all,

Thanks for the tip Aleks. Anyway, I have another question. When I visualize the computed derivatives using VisIt or Tecplot, it appears that discontinuities exist at the interfaces between elements. Is that normal or did I screw up something when setting up the calculation ?

Thanks,

JC

PS: Attached is a small portion of my computational domain on which one can clearly see the discontinuities. _______________________________________________ Nek5000-users mailing list [email protected] https://lists.mcs.anl.gov/mailman/listinfo/nek5000-users
