I have seen Roe-Turkel preconditioning being mentioned in one of the pictures at SU2's twitter account for low mach numbers. I was wondering how to enable it.
I tried specifying the following in the initial portion of config file for the simulation problem definition(got the clue from Cconfig class)
I am trying an external aerodynamic case using a mach no. of 0.062, using the incompressible formulation I obtained pretty descent results and was hoping for a better correlation with the preconditioning turned on.
Please correct me if I am going wrong.

Roe-Turkel preconditioning (ROE_TURKEL_PREC= YES) is set up to work with the compressible solver only when choosing also the Roe method for computing convective fluxes (CONV_NUM_METHOD_FLOW= ROE-1ST_ORDER or 2nd order).
Hope this helps!
