Dear all,
I am newbie to tec plot and please bare with my stupid questions. I have did LE simulation over a flat plate and my main aim is to find the transition region. I am struggling to generate results using tecplot. If someone could guide me it would be of great help. The questions are 1. I would like to get a time averaged shear stress along the flat plate ( I tried analysis -> perform integration -> time strands, but the result generated was not appropriate ) 2. I would like to generate the result image like the one I have attached. If any one could give some suggestion will be of great help., especially I am more concentrated on the point 1 (about time averaged results ) Kind regards, Kumar |

From what I can see in your picture, I would say that you should represent iso-contours of the Q-criterion (they can be easily computed) .

Thank you so much for the reply. Do I have to create Q-Criterion during simulation or after? Do you know how to setup in Fluent? BR Kumar |

have a look at this paper:
http://georgehaller.com/reprints/vortex.pdf It depends on what code you are using... (I'd need more information on that) you can create it both during and after the simulation Cheers |
