Bug? refineMesh boxToCell negative coordinates

lindstroem · June 20, 2011, 07:49

Hi all,

I am wondering if it is a bug or I am just "blind".

I added a simple testCase - a box [ (-1 -1 0) (1 1 1) ]

When I run refineMesh with

Code:

topoSetSources (

     boxToCell
     {
           box (0 0 0) (1 1 1) ;
     }

);

everything is fine, but if I change it to

Code:

topoSetSources (

     boxToCell
     {
           box (0 0 0) (-1 1 1) ;
     }

);

no cells are selected. Am I doing something wrong? Is it supposed to behave like that? Or have I just not searched well enough? Thanks for help!

I think your box is defined inside out like this, something like this may solve it:
box (-1 0 0) (0 1 1)

thanks, your right! Didn't know there's a "inside out" when a box is described with two points..

thanks!
