Hi All,

I need to do an optimization study on Auto component.
I have few question on adjoint solver.
1. Can we run Adjoint with Segregated solver or it only works with coupled solver ?
2. I run a air flow model on segregated and coupled solver i.e. I used same case with two solvers. Case with segregated solver converged in 2500 iterations while coupled solver converged with 15000 iterations. I didn't understand why it is happening ?
3. I tried to run by change in parameter of coupled solver i.e. Grid Sequencing, Expert Driver and Continuity Convergence Accelerator but no result in terms of convergence. It takes almost same number of iterations.

Can anyone please throw some light on above mentioned points.

Thanks in advance.
