Hi Shujie, Which solver are you trying to use? You should be able to use a triangle mesh with the quasi-3D approach, in which case you you could use NekMesh to generate your high-order mesh. You will find more information about NekMesh in the use guide (http://doc.nektar.info/userguide/latest/user-guidech5.html#x21-950004) as well as the tutorials on mesh generation (https://www.nektar.info/community/tutorials/). Let me know if you have any other question.

Now I want to use Quasi-3D approach. It seems that only quadrilateral mesh can be used in Quasi-3D approach. I tried to use Gmsh to generate mesh for NACA0002 airfoil. I have an example mesh. But I do not know which software can generate mesh like that. [cid:image001.png@01D55104.62821930][cid:image002.png@01D55104.62821930] I used to use Gmsh for mesh generation. But for NACA0002 airfoil, it seems it is difficult to generate a good quality quadrilateral mesh. If someone has good ideas, please let me know! Many thanks! Kind regards, Shujie
