Hey all,

I'm new to Turbogrid and I'm struggling to understand why, when I mesh a blade, the resulting mesh appears to be offset from the domain (as if it was rotated one half period). See the attached image.

I searched the forum and found from http://www.cfd-online.com/Forums/ans...depassage.html that the ATM Optimized topology causes the mesh to be offset from the geometric domain and that this is normal. My question is why? And is this reasonable? It seems strange to me that part of the domain is not being meshed... Does this have something to do with the periodic nature of the geometry? I'd really like to understand this before I spend a bunch more time on it... I don't want my simulations to be bad because the mesh was weird.

Thanks in advance.
