Hi Vishal,
In Gmsh after building the mesh you just click the "set order 2" option and
it will convert the elements from linear to quadratic. After this you need
to make sure none of the curved elements are self intersecting by
inspecting the mesh.
Thanks,

Hi Vishal,
Yes this behaviour is expected and has been reported by other DG and FR
research groups . As you coarsen the mesh while keeping the Reynolds number
constant you are relying more on numerical dissipation to dissipate energy,
rather than physical dissipation. If the mesh is extremely
Hi Jianguo,
I can try to help with your first two questions.
1) As mentioned by Junting the first thing to do when generating the 3D
airfoil mesh is to start by generating a nice 2D mesh. You then extrude in
the spanwise direction. For the initial 2D mesh you can build some
structured mesh
Hi Mahmood,
It sounds like what you are trying to do is not a valid way to use gmsh. As
far as I am aware, you cannot re-mesh a .msh file like that since the .msh
file does not contain the geometry, that is contained in the .geo file.
You need to have the .geo file that defines the geometry,
Hi Junting,
You should be able to make a prism layer in gmsh by creating a triangular
surface mesh on your object, and then using transfinite line/volume to
stretch this outwards into a volume of prisms coming off of the surface.
This is a bit difficult to explain here, but you can see an
