Hi Guys:
I want to know the part of the codes that is for computation of the surface sensitivity , including the surface grid sensitivity (probably inside SU2_MDC part) and the finally assembled sensitivity of objective function on every surface node, using the chain rule. Could anyone point out where can I find that part of the codes. Many thanks ! |

the surface geometrical sensitivity and gradient projection is done in SU2_GPC. In particular the surface sensitivity (finite differences) is done in SU2_GPC.cpp (line 137 and below, it starts with the loop over the design variables). The projection is done in the same file (SU2_GPC.cpp) starting in line 233… it is a very simple projection (a couple of dots products in the surface). Cheers, Francisco |
