[Nek5000-users] Setting up a case from scratch

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

Hi Praveen,

I would try building 2D mesh of the side wall of the channel with cylindrical 'hole' first in prex and then extrude this mesh in the spanwise direction with n2to3 tool.

Best.
Aleks

Hello 
I want to setup a case of 2d cylinder in a channel. I plan to do this way 


1. Make mesh in gmsh 
2. Convert to vtx 
3. Setup in prex and read vtx mesh. 
3.1 make curved sides 
3.2 set boundary conditions 


I have already tried all these steps partly. I want to know if there is any easier way to do it. Especially making curved sides and setting boundary conditions needs to be done per boundary edge. Is there a way to make it faster ? 


Thanks 
praveen
