unexpected geometry ...

Hi all,

I'd like to mesh a 2D-box which is composed of 6 different lines (4 for the top and down and 2 for the sides) with quadrangles.
When I'm using the Salome's "quadrangle preference" option it returns me an error that I cannot correct :

"Unexpected geometry. Face must have 4 sides but not 6".

I understand well what does it means, however, is Salome is unable to mesh such a structure ?
Is there is an other way to do so without cuting my box into two 4-sides sub-boxes ?

Thanks a lot lot for your replies.

Thanks for your reply.

I've unsuccesfully tried the Netgen option (see the attached file) which ... well ... does not seem to work in my case study.

I have split my surface into 4 edges regions and everything is fine.

Something odd is that you can do the calculation on "n-edges" regular contours (I mean boxes for example) and not for irregular ones.

Well, everything is fine for me now, thanks again.<br /><br />Post edited by: Delalleau, at: 2008/04/18 18:59

The expected file.
