Methods for creating cellZones and faceZones

Posted July 26, 2012 at 11:03 by kalyangoparaju

Friends,

I've been playing around a lot with the creation of cellZones and faceZones and here is what I have to report !

Till now I have found 3 ways to do it. ( I am sure there are more)

1. To use setSet utility and cellZonesSet and faceZoneSet commands.
This works amazingly well and creates the zones. A small problem can arrise if you are trying to set zones for an internal flow case and at the center of your geometry you have level 0 cells....

This is yet another one of my "rants on my blog" I do once in a while.

So today I was trying to reproduce this report: http://www.openfoam.org/mantisbt/view.php?id=590 - I was curious about this, because ICC is known for having great optimization on Intel processors (or at least it had in the past), as well as being completely free for non-commercial use on Linux.

The detail here is that I don't have an Intel CPU on my home computer. I've got an AMD 1055T x6 ...
