Hi,
Simply replace the Navier-Stokes makers in your config file with the following parameter:
%
% Navier-Stokes wall boundary marker(s) (NONE = no marker)
MARKER_HEATFLUX= ( car, 0.0 )
and so on for the rest of boundary markers.
NOTE: Normally you should find all the updates within the config_template.cfg file supplied with each release of SU2.
Hope this helps
Taxalian.

hi all,
I'm new user of SU2. I would like to make tests of the adjoint solver on a rear-view mirror to reduce the drag coefficient.
In SU2 v2.0, I can make a simulation without the adjoint part. I've upgraded my version of SU2 and I can't reproduce this case now. I don't find how to have wall without temperature like with MARKER_NS. To the car and the rear-view mirror, I've four boundary conditions (car, arm, mirror and mirror_plate).
If some body can give me some advices, I give my configuration file.
Code:
