[Nektar-users] Mesh order on curved boundary

Hi there, I'd like to use nektar++ to simulate 3d flow over a circular cylinder. but I'm feeling a little confused about the mesh order of curved boundaries. My puzzle is as follow: If SEM basis is 4-order polynomial, and the mesh, generated by Gmsh, is 3-order. it means the order of base function is higher than mesh order of mesh. is there any inconsistency in this case ? zhicheng
