Boundary Condition Problem using atmospheric module with not usual domain geometry

My Problem concerns atmospheric dispersion of tracers.
I'm using a losange shape outer domain, truncated on the ouest side to put an injection face.
I activate the atmospheric module for dry atmosphere, with ouest sides with inlet profiles (met from data), except for the injection face, and east sides as outlet profiles (+automatic inlet/outlet).
I get an error message on the first face (type 0 at (0,0,0) instead of 6: wall) encountered with incomplete or incorrect boundary conditions definitions.
When I use profiles without atmospheric module, computation proceeds.
Is there a limitation regarding the shape of the outer domain ?
