Hi,
I'm studying the "continuous" adjoint method by reading Dr.Soto's article titled "ON THE COMPUTATION OF FLOW SENSITIVITIES FROM BOUNDARY INTEGRALS". http://www.scs.gmu.edu/~rlohner/page.../reno04adj.pdf I have a question regarding this article. Could someone answer the following question? Q)Question about the derivation of the adjoint boundary conditions My understanding is that the adjoint boundary conditions are derived so that all the boundary terms of equation (13) are exactly canceled at all boundaries. I think we need the value of δu and δp at boundaries when deriving the conditions. Could you tell me how to know these values? It says in this article that "δu=0 on S and on the outflow (Γout)(δu is the test function associated to the adjoint velocity, then it is zero wherever ψu is prescribed)" but I can't understand the meaning of this description at all. Thanks. |
