[Nek5000-users] Placing cyllinder near wall

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

Hi all,

I'm testing the effects of near wall obstacles, but I'm struggling to
decide for a adequate method to build the mesh.

The main goals are to have a hyperbolic mesh spacing perpendicularly to the
the wall and easiness to place a cylinders inside that mesh close to a wall.

So far I've been using makenek to build a series of boxes and replacing one
with a cylinder box. The main issue is that grid size is hyperbolic
everywhere, except in the boxes that lay in axis of the cylinder, where the
mesh becomes uniform in order to fit the cylinder generated with makenek;
and that the custom Fortran script that generates the .box files is quite
bothersome to modify freely.

I was wondering if nekenk could be used to place a cylinder inside a box
with user-specified distribution or if you could recommend a meshing
software or code that could do the job (hopefully linux-friendly and free).

Regards,
*Nicolás*
