Ok im new to Gambit or any other CFD software. But im required to use this fro my project. Hope to get some help here.
I tried a couple of times creating the mesh using the airfoil SG6042 .with the tutorial from Cornell University. But i keep running into a problem with the point G which is created at the tail of the airfoil. The problem is that i cannot subtract the airfoil from the semicircle portion. It gives the error : "ACIS error 8029:inconsistent edge face relationships". If i were to shift it a little i could subtract it but meshing takes a long time and i can only do it using PAVE method not MAP. The tutorial is found here http://courses.cit.cornell.edu/fluent/airfoil/step1.htm Is there a way around the vertex point G. I tried using the same airfoil given it has such problems too. Somtimes vetices gets deleted. Thank you. Last edited by Arti; April 3, 2009 at 04:17. |

I assume there is a problem with the fact that G belongs to the airfoil and also to the semi circle
Try this: Substract the airfoil from the whole big domain (ABCDEFA). Then once it is substrated (ie the airfoil is a hole --> shaded mode), you have to split the face along the edge (AE), G is aligned on this edge. And then the same wit (GC). It should be ok |

Hi all,
I am having trouble meshing 2D boundary layers in Gambit. The geometry I am working with is the wind airfoil. I have flow inlet and outlet, and inlet/outlet is planar and roughly rectangular. The entire geometry is a sort of rectangular shaped outer airfoil. I can create but when I use the "View 2D Boundary Layer" tool in Gambit, my boundary layers will not even appear in the selection list and cannot be added by shift-left-clicking on them. Does anyone know why they cannot be added to the list?
