Modifying Turbulence models to account for anisotropy

  I'm currently studying compressible flows, and there is a lot of literature that suggests that there is anisotropy in supersonic compressible flow. I am currently using the k-w-SST turbulence model, although currently, I have to calibrate the closure coefficients to match my experimental results. Is there any way to modify the equations that I solve by adding a QCR (quadratic constitutive relation) model or say including additional anisotropy terms in the Reynolds stress calculation?
  I think calibrating the coefficients to my case is good enough, but it would be nice to see if its possible to add these.

  Hello,
  You might want to try with the RSM model, which shows greater accuracy for anisotropy is taken into account. Here is more information: 4.10.1. Overview (ansys.com)
