Yes, it's the mesh. Min ortho quality of 0.05 is considered to be poor quality, you're somewhat below that. Similarly aspect ratio has some leeway for inflation, but 1,300 is very high. 

Looking at the second image, check the walls bounding the flow that cut the structure don't have narrow gaps or crevices which then cause the skew cells.Â
