However, I met a problem. I’m not sure how to customize my own 2D mesh, say change the flow domain, radius and position of cylinder. I have read though your tutorials. It seems like I need a CAD .step file to achieve my goal. But I also noticed that Nektar++ can generate meshes of NACA wings. So I’m wondering if I can do the similar things to generate meshes of a cylinder. Best, Zhikang
