Hi,

I am trying to mesh a propeller blade using ICEM CFD. I tried O block topology to mesh my geometry but the quality was not good. So I was recommended to try Quarter O-grid (aka Y block). The periodic angle is 32.72727 (11 blades). The flow is along X direction. I drawn Quarter O-grid using four faces. I have attached few pic, Figure1 represents the geomentry, Figure2 - initial block round the peopeller domain. Figure3- quater O-grid by using four faces (inlet face, outlet face, left side periodic face, bottem face), Figure4-after asssociation of vertex with points. face, two periodic faces and outlet face). I don't known how to fix the quarter O-grid to capture the propeller blade geometry. I have seen some post about Meshing wind turbine but I didn't get an idea to mesh my geometry. It will be great if will be great if someone help me to fix my problem. I have attached my geometry and blk file in the following link.

Thanks in advance for your information. please help me to mesh this geometry. I am trying for the past 1month to mesh this geometry.
