[Nek5000-users] Create mesh for cylindrical domain

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

Hello all,

I am new to nek. I have created a mesh using genbox. I want a run a simple
case with 3d channel flow. I need information on giving the BC element wise
for all the grid points. How to work on with .usr file.

Thanks,



Ravi Kiran Pendyala,
