Hi Domen, Thanks for the helpful advice. I opened the autogrid file within that directory and got an intersection error between blade and hub shown below. It seems it is as you say in the second point. In your 2nd point, how does the blade being replaced by a shorter geometry occur? In this file, I then went to expand the blade to intersect the hub. However, expanding the blade resulted in an unusual shape near the hub. It did not end up fully intersecting the hub either. Expanding only the hub also gave an ''adapt units'' suggestion (Although the parasolids geometry that I linked the initial mesh had units in metres). I increased the sewing tolerance and adjusted the expansion ratio but still did not fully intersect the hub. Expanding both hub and shroud did not work either: In addition to the intersection error, the job file also mentioned that there is a self-intersecting error: Not quite sure how that occurred. So far, the only possible solution I can think of is to adjust the blade geometry in Solidworks to intersect the hub, and restart from the beginning. Is there maybe an easier solution to this problem?
