Automatical change of the angle of attack
 

I´m interested in getting different results of a profile working at different angels of attack (2D). To do this I´ve created another coordinate system (the one that says which one is the fluid direction, velocity...) and I rotate it in each simulation 5º.
It is possible to change this automatically? I mean, when the simulation arrives for example to 4k steps, the simulation by its own it is going to rotate the coordinate system and start it again (saving the previous results of course).
Thanks!

I would like to know the same thing as I want to create polar plots of diferent airfoils to use them with BEM.
Hope someone can help us

Well... you could use a field function to define you velocity direction as a function of iterations and use auto save to save your sim file...

Or you could use a java macro to do that for you....

Hope this helps!!

When I want to simulate different angles of attack for my external aero analyses, I change my "Flow Direction Specification" to "angles" and then change the "Rotation Convention" to "Yaw, Pitch, Roll". I then update the angle. Once you figure out how to do it, java it.
