Hello GMSHers!

I have been trying to create a high quality quasi-2D (single layer) airfoil mesh in GMSH for use in OpenFOAM. It has a structured boundary layer and an unstructured far field region. When I try to extrude the unstructured far field region in the Z-Axis to create a single layer, GMSH creates two diagonal lines across the trailing edge of the structured boundary layers and produces two 'cannot find extruded vertex' errors. Please see the attached pic and .geo file.

Any suggestions on how to resolve this issue, better ways to create this type of hybrid mesh, or any other critiques or recommendations are greatly appreciated!

Thanks very much for your help!

Best Regards,
Henry

While I have not found a solution to the original issue, it does appear a high quality hybrid (structured boundary layer / unstructured far field) 2D airfoil mesh can be created much easier using the Boundary Layer Field function. See attached geo file.

If anyone has a solution to the original issue, it would be nice to know, as the surface normal extrusion technique does seem to provide more control over the form of the boundary layer mesh.

Thanks,
Henry

Hello,

A third option would be to use Gmsh to generate the unstructured (tet) mesh, convert to OpenFOAM format with gmshToFoam, and use snapyHexMesh to add the boundary layers. This has worked for me in the past - might be worth trying for your case.

Kind regards,
Peter

Hey, first I want to thank you because your file helped me a lot in trying to make the same kind of mesh for turbine blades. Unfortunately I am unable to get the actual boundary layer part working. And I think it is primarily because I don't know the numeric designations that GMSH applies.

You also stated in your file that you got the numeric designations from the GUI as can be seen here below. But is there any way of getting these numeric designations without using the GUI? Because my goal is to make automatically a mesh with GMSH and run it in SU2, so this doesn't work if I have to look up the numeric designations. Since I will be using SU2, I also don't need to extrude the mesh to get a "fake" 3d mesh right?

//Define physical surfaces - numeric designations from GUI
Physical Surface("back") = {201};
Physical Surface("front") = {233};
Physical Surface("top") = {224};
Physical Surface("bottom") = {216};
Physical Surface("inlet") = {220};
Physical Surface("outlet") = {212};
Physical Surface("foil") = {228, 232};

Good morning,

This is my first post so I am sorry if I am doing it wrong.
Besides, English is not my mother tongue so my apologies for any mistakes or if I seem rude, this is not the case.

Well, I am currently working on an NACA0012 and already did it with the SnappyHexMesh tool from OpenFoam.
Now, I am looking for meshing the profile with Gmsh.

Firstly, thank you for that example. It Helped me a lot.

But I am faced to some issues. I tried for a week to find a solution but didn't find yet.
When I mesh the profile with boundary layers, it works fine except at the trailing edge.
Indeed, the mesh is "blue" (means it is not correct?) but even more, I would like to have two things :
1) Is it possible to have the same refinements at the trailing edge thank all around the airfoil for the boundary layers ?
2 ) Is it possible to have the same refinement level at the trailing edge thank all around the boundary layers because if you watch the image attached, there are few cells after the boundary layers at the trailing edge.



I attached an image to help you understand.

I am sorry if you have already answer to that kind of questions several times and if the questions are stupids but I am quite lost...

Thank you very much.

Best regards,

Greetings to you all,

Well I tried to fix my problem by creating 2 boxes which is much better.
The problem is I don't know how to extrude the surface to make the two new surfaces in one. I tried the tool Compound Surface but the back and front surfaces look very weird.

So my question is , how to create 2 boxes to have 2 different refinement levels and make it work for OpenFOAM ? ( Means have the inlet, outlet, .. just at the external box).

Thank you, everyone.

Best regards,



EDIT : I figured out to generate meshing. Looks there is 2 boxes but when I cant to create the boundary layer, the meshing is very bad. (see images attached)

Anyone has a solution?
Thanks

Has anyone figured out how to do local mesh refinement near the trailing edge of the airfoil? I have tried giving different mesh size values to the points that are used to define the trailing edge but this seems to be overwridden by the size specified for the points around the airfoil body...

Good afternoon Jack001,

Sorry for my late answer.

For the trailing edge, I did not succeed to refine the circle part of the boundary layer but it was not a problem to converge all the calculs.
But I understood like you that the first and the final point of the line define the refinement of the entire line (line or spline).
Knowing that, What I did to refine several part of the boundary layer differently is to define the foil with different lines and splines as I wanted to refine

Example :
Spline(5) = {1000:1059};
Line(6) = {1059, 1060};
Spline(59) = {1060:1137};
Line(60) = {1137, 1138};
Spline(61) = {1138:1174};
Line(62) = {1174, 1175};
Spline(63) = {1175:1288};
Line(64) = {1288, 1000};

I attached an example to that message.

I hope you understood my english and I helped you a little bit.

I need calculated and simulation an airfoil Naca 0012, using app QuickerSim in Matlab. But i have'nt license, so i hope someone can help, please!

you have to manually edit the script:

Field[2].FanPointsList = {1, 3, 4};
//+
Field[2].FanPointsSizesList = {4};
//+
Mesh.BoundaryLayerFanElements= 20; %this is the line you need to add manually to obtain the effect
