[Gmsh] 2D Axisymmetic gird in gmsh to 3D grid?

CFD-Lover · June 30, 2016, 03:23

Hey All,

I have preformed a 2D axisymmetric simulations in openfoam using gmsh of the flow over a c-d nozzle. The simulation gave reasonable results when I validate it. My aim now is to create a full 3D mesh using the same meshing tool i.e. the same mesh that I created in 2D. I was wondering if there is any way to create a full 3d mesh using the same mesh using rotation. I have tried to rotate it but the problem is that the mesh got a little bit messy. Has anyone dealt with the same issue could give some hints?

Thank you,

Is it possible to get a real 3D mesh starting from a 2D axisymmetric mesh in gmsh?

Kind regards,
