3D CAD airfoil geometry using star-ccm+

meem · July 21, 2016, 16:40

Hi, I have made a 3D airfoil part using star-cm+ own 3d CAD. I plan to change the orientation of the airfoil by changing its angle of attack after mesh generation. Will I have to regenerate the mesh after changing the angle of attack each time? This is my MSc project and I am quite new to cfd, help is much appreciated.

Yes you can make it a parameter in the CAD model and if you setup the work flow it becomes a simple remesh/ new run but you can also rotate your region for each new angle, you should be using a c-grid shape for your domain,

thank you marmot. With your guidance I was able to find all the details in star-ccm+ tutorials.
