Dear NEKs;

I am trying to run a simulation of a turbulent flow in a straight pipe
in high Reynolds number (Re_tau = 1000). After generating the grid with
PRENEK and extrude it using n2to3, the mesh ended up with 4,495,920
elements. It compiled properly; however, trying to run it, hanged up in
the last stage:

I was wondering if you could help me with that. I attached the run
logfile and also genmap.out.

Many thanks
