My unstructured mesh is working well until the lenght of the control volume is smaller than 10 times the profile chord, then it became irregular on the profile corrupting the mesh quality. My target is to create a control volume between 25 and 50 times chord dimension. I attached the .geo file and a screenshot of my problem. Where could be the problem? I think my code is quiet simple and clear but maybe some option is required. Thank you Attachment 48297 Attachment 48298 Last edited by gex; June 15, 2016 at 11:52.
