Hi Guys,
My names is Anthony and i am currently studying for my undergraduate degree. I am trying to do analysis of airfoils using ICEM and FLUENT. I am trying to do a 2D analysis on a multi-element airfoil, and am having problems creating the blocking for such an airfoil? As in 3 separate elements with their own blocking. For a single element i have no problems. For this do i have to use the surface blocking instead? and if so can i then create blocks so i can define my boundary layer? This may seem like a very elementary problem as i am fairly new so all help is appreciated Thanks a lot Anthony |

Hello Anthony,
i think you can create the blocking of the multielement airfoil the same way you did the previous airfoil (with a planar blocking). Except, your blocking will become more complex. with regards, Sebastian |

Hey Sebastian,
Thank you for the reply. O Okay as i was trying to do this but i kept and getting confused. Do you know what strategy you would undertake this by any chance as the current method i was using was to use a Ogrid what i would split and then collapse the vertices and associate this to the element. If i try this method with the 3 elements it gets very messy and i lose track on what i mean to do. Maybe i just need to keep practicing then? |

Giving a general approach on how to mesh your geometry without having a look at it seems difficult. Moreover, I only have meshed a few airfoils (just simple ones) before myself.
To give you a few ideas how to design your mesh, have look at these pages: http://www.pointwise.com/theconnector/November-2012/Meshing-for-Aeroacoustics.shtml http://sandi.co.in/v2/home/projects/aerospace/nhlp2d/ http://sandi.co.in/v2/home/projects/aerospace/omar/ Following those examples, it seems to be a good idea to keep the c-grid structure. |

Thanks Sebastian for the links and help.
Unfortunately it seems a bit out of my depth for now so will not be continuing that element of the project. |
