Ladies and Gents,

Currently I am looking to post process a batch of results utilising the same geometry and need to attain the a way of outputting the following, using data I have extracted from StarCCM+:

1) boundary layer thickness (delta), Momentum thickness (theta) and shape factor (H).

Essentially this as far as i can see requires me to know the boundary layer thickness, and the rest can be interpolated from the corresponding location for other parameters. I have an approximation for delta being roughly equal to 1.936ymax (the ymax being essentially a velocity gradiant based on wall distance).

Wall distance, velocity are all outputable from Star but I am at a loss how to script Tecplot to search for the boundary layer edge.

2) Plots of coefficients (CP,Cf etc) over a blade relative to the displacement along the blade suction surface. -Is the way to do this by using a duplicate surface which is altered so exists in one plane? (e.g. Z=0)

Hope the above makes some sense, and welcome any ideas. even if it just provides food for thought.

Thanks for any help in advance,

Martin
