Default Fluent Adjoint Solver for compressible flow

Hey everyone! I have been trying to solve a simple min. drag optimization problem for flow past a triangular wedge at Mach 4 condition. It appears that adjoint solver cannot handle pressure-far-field boundary condition so I changed it to pressure inlet/outlet conditions. The fluent solver itself converges but the problem lies with Adjoint solver.

It shows multiple warning saying it cannot handle
1. density based flows
2. pressure inlet based b.c. etc

Is there a way to run compressible flow calculations in adjoint solver of Fluent??
Please suggest.

In current version of Ansys Fluent, only incompressible solver is supported in Adjoint solver.

with R15 the Adjoint Solver supports the energy equation. You can simulate cases with low compressibility (Ma<0.7). This works good!
