Meshing trailing edge of aerofoil

Hey,
when using the boundary layer tool in Gambit to mesh the near wall region of an aerofoil I experience problems at the trailing edge. The x-direction size of the first cell downstream of the trailing edge appears to be equal to the y-direction cell size along the surface. For y+<5, the latter is very small, i.e. 1e-5, which means that the spacing of the cells in the x-direction downstream of the trailing edge is equally small. This, in turn, renders problems at the interface of the boundary layer and the outer region when using an unstructured mesh - the resolution is poor, skew angles etc. Does anyone know how to change the configuration, so that the x-direction size of the cells downstream of the trailing edge can be increased (and is not equal to the y-direction size of the cells along the aerofoil surface)? Many thanks for your comments in advance, CC |

Wifi Lee,
thanks for your reply, but I don't see how I can add an attachement here? Would you be happy to send me your email address, so that I can send you the file? Alternatively, could you explain how I attach the file using the forum's email? Cheers, Claudio |

Sorry, but I hadn't been informed that there'd be a bill. In that case, please just leave it alone.
