Hello Everyone,

I simulated a turbine with a yawed flow to understand the wake deflection and propagation. The wake generated is deflecting in the direction opposite to what everyone else is reporting. I am not able to figure out what the problem might be. Did anyone face a similar issue anytime? Can someone help me with it.

I checked for blade rotation, mesh quality (y+<5), boundary condition (inlet is uniform velocity and outlet is 0Pa static pressure).

Thank you.

Please post an image of what you are getting and what you expect. Also your output file.

By the way - y+ is not a measure of mesh quality. That is a measure of near wall mesh resolution. Quality is things like aspect ratio, orthogonality, expansion ratio and factors like that.

I have attached the image of the expected and the image of what I am getting. I have changed the extension of the output file to .txt as it was not allowing me to upload the .out file. Thank you.

Please have a think about what you are posting. Your image is a mystery. I have no idea what that shows, how you set it up and what it means. You are going to have to explain what is happening.

Gert-Jan will become famous soon enough
The pictures look like the upper part of a thigh bone . So, for me it could be a stress calculation as well.
