[snappyHexMesh] STL format in SnappyHexMesh

samiraamiri · July 17, 2015, 09:32

Dear all,
I generated a STL file with Salome-meca 2015.1, but I don’t know how should it be done …,I sketch a curve consist of coordaniate of points of airfoil and connect them with spline curve,,extrude it 1 cm around z axis so export it in STL format but it seems strange
I have attached the picture
Can I use it for snappyHexMesh?

Best regards
Samira

Hello Samira,

Your STL must be closed in order to generate a mesh for an external flow, as I imagine that what you are trying to do.You need to generate triangles on both sides of the wing.

Dear Daniel
Thank you very much for the reply..yes,,I'm working on airfoil shape optimization for wind turbine by openfoam..
how do I generate triangles on both sides of the wing?
Can you please provide me step-by-step instructions for creating it?

Thanks

Hi samira,

I found a good step by step tutorial by youtube https://www.youtube.com/watch?v=ObsFQUiVi1U

edit: I think Daniels link fits better, because snappyHexmesh is probably not the best program for your problem.
