Impeller fluid domain mesh deformation
 

Hello

Im trying to run CFD analysis on the impeller. The impeller was imported as a step file and the fluid domain was created manually. I created the a mesh with a body size of 0.5mm and method of "body fitted cartesean" and the inflation was created automatically due to the method chosen. When I opened itof CXF pre the impeller blades look damaged. Is this a a visual bug or an actual mesh deformation. I have attached images. Thank you for your help in advance.

Could it be that the mesher removes cells below a certain size that would be required at the blade tips?
