[Nek5000-users] solver tolerances and norm of residual

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

Hi Nek users,

I am new in using Nek5. I have succesfully simualted the lid-driven flow,
rayleigh-bénard in a square cavity and laminar poiseuille flow. All of
them were 2d cases. I though it would be straightforward to move from 2D
to 3D simualtions but I have not been able to run a 3D poiseuille channel.
I am obtaining an error on Helmoltz solver even in the first iteration.

Please, find output, usr and box files attached.
Thanks in advance.
