Hi Alessondro,
Just to be clear, I attach the mbox.box file that I used. It works with the current repo
version of genbox (and earlier ones).

Hi Paul,
Thank you so much. Are the BC's correct?
I have slightly modified your script and I get the following error. What is wrong in your opinion?

Hi Alessandro,
Here is a multi-box file example that will generate something similar to what you're
after. You can edit to suit your needs.

.... PS ---- Be sure that you have 3 characters (counting spaces)
for each BC.
The "right upper" "right center" etc. are just comments.
"Box" is a keyword, however... (so to distinguish from cylinder, etc.)

I can think of two options:
- Create the three different boxes with genbox and merge them with nekmerge
- Create the whole mesh with your favorite meshing tool, export it as EXODUSII and use exo2nek

Betreff: [Nek5000-users] How to assembly different geometry
Hi All,
I would like to generate a mesh as Figure 2 in
http://www.mathematics.uh.edu/docs/math/NASC-preprint-series/2015_2016/Preprint_No16-54.pdf
If I build three different boxes, how can I then assemble them? Could anyone please help me?
Thanks,
Alessandro
