open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

I'm trying to run my first simulation using TELEMAC. I used Bluekenue to create the geometry and boundary conditions files. However, when creating new project with fudaa, I get the following warning:
"Cartesian grids are not supported"



I went back to bluekenue and realized that my selafin and bc file, did not have a coordinate system assigned. I created again the selafin and bc files, after having assigned an UTM system to them. But still the same warning shows up, even when it says that no errors were found. I realized that bluekenue always shows at the bottom that cartesian coordinates are being used...

So I'm wondering:

1. How to make bluekenue to save my selafin and bc file in other coordinates system? (the problem seems to be only for the .cli file and bluekenue doesn't give me any option to set a coordinate system for such file) or how to change the coordinates system in which bluekenue displays everything?

2. If I just skip that warning, might that be source of errors during the computation with TELEMAC2D?

I just add that, after showing that warning, the mesh and geometry are correctly displayed in FUDAA...but I have no idea on the implications of this warning.

Thanks
