Hi

I am doing CFD analysis of a propeller.

It is a steady state analysis hence i am using frame motion. I have created 2 domains, the static and rotating domains.

This is the mesh i have created,

When i load this mesh into fluent, i get these messages,

What do these mean? How should i eliminate them?

Also, when i check the velocity contours, i get these strange areas at the interface of the rotating and static domains which i think are because of the above messages. Am i wrong? Have a look at these images,

Lastly, the thrust value that i get is approximately 50% of the actual value. So there's a big error here.

Please help me with this problem, i will be extremely grateful!

Regards & Thanks
