Area mesh in ansys 12

Hello to all,

I have a problem in meshing area in ansys. I have craeted two areas perpendicular to each other in global xyz cartesian system. I can easily mesh the area in xy plane but if i try to mesh the area in yz plane it gives error message that the area is not parallel to global xy plane. I tried going for local coordinate system, but it is also not working. Can anybody guide me regarding this.

Thank you
