[GAMBIT] Problem sweep 2D airfoil to 3D

nerbur · May 18, 2012, 03:58

Hi all,
I am trying to create a 3d airfoil from a 2D mesh.
For do this I use "sweep face" tool. As you can see in next image, the volume is created correctly in first and last face, but when Gambit try to sweep the intermediate face appears the next error.

ERROR: The faces are not coincident
Please try disconnecting the face being swept from upper topology

I'm also tried to copy and translate the mesh and then create the wireframe, but still giving error with face that contains the foil when I try to create the voulme.
I tried to do this operation splitting the middle face but ever I have a one face that can't be extruded.

Greetings

are you trying to sweep all faces at the same time? from error, I can infer that you are sweeping side faces first and then the inner surface with airfoil?

Yes, I sweep the three faces at same time but only first and last extrude.
If I try to sweep interdependently the result is the same.
Indeed, I try to do a mesh with only one face, but I ever have an error when try to sweep a mesh that contains the airfoil.

did you try to sweep the faces in volume from middle first?
If it failed, try to merge the surface with airfoil with the disk, and retry to sweep.
Sweep both volumes at extremities once the one in the middle is successfull
