[Nek5000-users] Define objects in prenek

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

Hello,

I have a question to "prenek". I'm trying to define a grid of a rigid 
sphere in a channel (similar to the configuration in the paper of Zeng, 
Balachandar, Fischer (2005) "Wall-induced forces on a rigid sphere at 
finite Reynoldsnumber"). To my knowledge I have to generate the sphere 
grid with CURVE SIDES > SPHERICAL MESH ("sphere.rea") and then the 
channel grid ("channel.rea"). Finally I have to insert the sphere grid 
as an object into the channel grid. But I don't know how to do this.

Hope you can help me. Thanks a lot.

Best regards,
Fred
