Hello,nThe minimum orthogonal quality of 0 is bad. I'd first identify the cells with these poor quality cells (in the range of 0 and 0.1). This will tell you whether you need better local control or if you need to simplify your geometry in these regions. nRegarding the incorrect rotation, please share a screenshot of your problem set-up and a schematic representing your geometry here in your response. As an Ansys employee, I will not be able to email you to get these details. It is possible that your center of rotation (through which your rotational axis passes) is not properly specified. You might want to get the correct coordinates. You should be able to do this from your CAD tool (perhaps, Ansys SpaceClaim might help).nThank you.nKarthikn
