Adjoint Solver in StarCCM+

Moti · May 24, 2012, 18:22

Hi Everyone;

Does Star-CCM+ have something similar to adjoint solver in order to postprocessing of external flow anlysis of a car and grab the problematic area of the model? If not, what do you suggest as the best way to detect the aerodynamics problematic areas of a vehcile after an analysis?

Your feedbacks are greatly appreciated.

I know that cd-adapco is thinking about this, but not really working on it at the moment. hope this helps u. Their is an alternative if u want to use open foam with an open source adjoint solver, also in ansys fluent is a adjoint solver included.....

Thanks, but can open foam read the simulation file of star-ccm+?

No, open foam cannot read star-ccm+ files.I do not know a library which supports this, but maybe I am wrong and someone here knows this better. I am also interested in this question :-)

There are several parameters like Turbulent Kinetic Energy or Dissipation rate where you can locate the important areas or areas u could work on. Also the Entropy in energy equation produced by dissipation term is very intersting. (the fomurla depends if you are using ideal gas or constant density). For Aeroacoustics the Diploles on surfaces and the Vortictiy can give you good hints...
