I am doing structured meshing on axial turbine with tip clearance. I did the association, blocking and O-grids successfully. However after providing first cell height and growth ratio. The negative volume elements formed in my domain. The negative volume elements are mostly formed close the tip clearance region.
Please help me to rectify this problem.
Try to reconfigure your bloks close to tip clearance (for example split in two or more bloks).
Thank you for your reply Djordje Novkovic , I ll try and come back to you.
I consider that you need to check your geometry model firstly. Is there a tiny gap between one curve and another one? I advice you to repair your geometry after you import it to ICEM. Can you show a figure about your model? That is easy to know the problem.
