[Nek5000-users] The first time step in a Nek file must contain a mesh error

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

Hi

  Thanks a lot for the reply and it worked.

I have couple of more questions

1) How can I create a .rea for a specific geometry say ' A sudden 
expansion pipe ' or a ' Diverging pipe '

2) What tool I should use to create that mesh.


Thank you
