Continuous Adjoint - Incomp_NavierStokes

pedropcb13 · July 29, 2021, 05:50

Hi,

Are there any Incompressible examples using the Continuous_Adjoint formulation?

In the TestCases Repository I found only compressible examples and the case I am trying to run is not working.

Regards,

Pedro.

SU2 does not have an incompressible continuous adjoint.

Thank you for answering.

SU2 does have an incompressible continuous adjoint (or at least it used to have one in the past). It is described in
Shape Sensitivity of Free-Surface Interfaces Using a Level Set Methodology. Francisco Palacios, Juan J. Alonso & Antony Jameson. AIAA Paper 2012-3341, 42nd AIAA Fluid Dynamics Conference and Exhibit, New Orleans, LA, June 25-28, 2012.

In fact, I even validated it against analytic incompressible adjoint solutions here

and here
