Default iteration on angles of attack

Hi,

Does anyone knows how to program in Fluent-Scheme so as to iterate a flow calculation around an airfoil on angles of attack ranging from 1 to 20 degrees for example, using the same mesh ? I also need to save the results of the calculation in a different file at each iteration.

Thank you in advance

Vincent.

Hi. you can use a define profile macro and hook it to your far-field bc. Luca

Run: fluent 2d -i angles.jou >& report_forces.txt

File "angles.jou" contain something like this: ;------------------------- rc airfoil.cas rd airfoil+1deg.dat ; ------------------------ (define tang 0.0349) /define/boundary-conditions velocity-inlet velocity-inlet-1 yes yes no 31.884 no 1 no tang yes no 1 no 0 q it 1200 wd airfoil+2deg.dat

/report/wall-forces 1 tang /report/wall-forces (- 0 tang) 1 /report/wall-moments 0.25 0 ;------------------------- ... repeat for angles 2-20 deg ;------------------------- exit yes

So there is no way to use a do loop that would save me a lot of time repeating the same script for the rest of the angles of attack ?
