[Nek5000-users] Pipe with expansion

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

Kamal,

I've added an example for a step-type expansion in a pipe.  New example directory
is nek5_svn/examples/expansion, with a README.

If you want a standard diffuser, I would use mesh-morphing, as outlined in the
nek primer, which can be found on this page:

http://nek5000.mcs.anl.gov/index.php/UG#Documentation

I've also automated our turbulent outflow bc treatment -- one simply provides an
expansion factor (typically ~ 1.5) and two persistent arrays to turb_outflow(), which
is now in navier5.f.    This can be useful when very strong vortices are leaving the
domain, which is possible for certain diffuser flow conditions (and others).

Paul

Subject: [Nek5000-users] Creating a Mesh

Hi

Can some one please help me in this because I am new to nek

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
