[Nek5000-users] genbox question

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

Hi,

I am struggling with genbox to generate a mesh around the cylinder, which
could be used in the example ext_cyl as the file import.rea, but with a
mesh refined or more coarse.

base.rea
2                       spatial dimension
1                       number of fields

3 -24 1                 nelr,nel_theta,nelz
.0 .0                   x0,y0 - center of cylinder
ccbb                    descriptors: c-cyl, o-oct, b-box (1 character +
space)
.5 .55 .7 .8            r0 r1 ... r_nelr
0 1 1                   theta0/2pi theta1/2pi ratio
E  ,E  ,E  ,E  ,        bc’s (3 characters + comma)

I am wondering how to define the boundary condition here.
E   ,E   ,E   ,E   ,
or
E   ,E   ,E   ,E   ,W  ?

I slightly modified some lines in mknek to take into account of this new
file, so everything can be run automatically. But I got a very strange mesh
here. Some parts are missing.

Can someone help me out?

Just download these files and run ./mkmesh

Thank you very much in advance.
