A question about RANS Adjoint test case on RAE2822

Tommy Chen · May 25, 2013, 00:06

Hi Guys

I have carried out a test on the RANS adjoint feature with RAE2822 airfoil using v2.0.4, the drag has been reduced, however I noticed that the airfoil became even thicker thant the initial airfoil.

I remember that Economon mentioned that the geometrical constraint is a new feature in the version 2.0.4, so I want to ask that is this due to that new feature?

Hi Tommy

I also tried RANS shape design on RAE2822 airfoil with SU2 2.0.4,
but I obtained only about 2.5 % drag reduction (Cd reduction from 0.0143
to 0.0131). How much reduction did you obtain ?

Thanks
Anant

Hi Anant

The drag reduction of my case is a little larger than yours, which is about 20 counts. Could you upload the pressure distrubtion comparison of the disigned and the initial one?

Hello

I am new to Adjoint
Can you please upload the test case
