Hi,

When using th Transition SST turbulence model, it is possible to introduce, in the form of UDF, new correlations (user correlations) for Re_theta, Flength and Re_theta_c .



The two last correlations are function of the local transition Re_theta_tild, obtained from a transport equation.


I need to know how to access the values of this parameter (Re_theta_tild).


Thanks.

I have the same problem, have you solved it?
