cfd-jg is on a distinguished road
Hi,


I have downloaded the compiled version of SU2 v.8.0.0 on Ubuntu 20.04. I am following the constrained shape design of a transonic inviscid wing at a cte. CL: https://su2code.github.io/tutorials/...ained_ONERAM6/


In the goals section says this:

"The following SU2 tools will be showcased in this tutorial:
  • SU2_CFD - performs the direct flow simulations.
  • SU2_CFD_AD - performs the adjoint flow simulations.
  • SU2_DOT_AD - projects the adjoint surface sensitivities into the design space to obtain the gradient.
  • SU2_DEF - deforms the geometry and mesh with changes in the design variables during the shape optimization process.
  • SU2_GEO - evaluates the thickness of the specified wing stations and their gradients.
  • shape_optimization.py - automates the entire shape design process by executing the SU2 tools and optimizer."
However, I have realised that the SU2_CFD_AD and SU2_DOT_AD tools are not in the compiled version. Does this mean that I need to compile the source code by myself to be able to use adjoint shape optimization?


If this is the case, how can I do this? I have already tried following the tutorial on the website but it is not very detailed and I always end up with some type of error.


Thank you for the help.

yes.
If you are currently working in windows, then switch to linux. Windows is not a research/development environment.

I am using Ubuntu 20.04, still need to build the code from source?

In linux, just compile with AD support:
Code:
-Denable-autodiff=true
