[Nek5000-users] Re : CYCLIC BC for bend pipe

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

Hi Paul;

Since I am using Prenek to generate the base mesh for the pipe in X-Y
plane, and then extrude it in the Z direction using the n2to3 tool, is
there any easy way to change the orientation of such a mesh based on
your suggestion? Or maybe I need to start generating the grid from the
very beginning in X-Z plane?  

Best regards
Azad


PS - be sure that the rotation preserves the right-handed
coordinates of the original system.
