Spalart Allmaras Gamma Re Theta Model
Hi SU2 Users,
I have tried to compute the NREL S-series wind turbine airfoil s809 test case available in SU2 v2.0.3 developers release.
The transition model implemented seems to be the γ−Reθt−SA model, introduced by Medida et al.
The problem is that the simulation diverges everytime few iterations and the residual of SA-eddy viscosity results in nan.
I tried to adjust the intermittency factor and the freestream turbulence intensity but does not help at all. I think this should not be the case normally at AoA=0°.
May be the model is not yet implemented completely or i don't what other issues causes the simulation not to converge.
May be it's also a good idea if we can have an input parameter that defines the freestream viscosity ratio i.e. mu_turb / mu_lam
Waiting for your reply.
Thanks in advance.
The transition model is not yet fully implemented and is not ready for use. Sorry for the inconvenience.
Thanks for the reply and info. Hope this will be available in the SU2 regular version release.
γ−Reθt−SA/SST turbulence model
Is the γ−Reθt−SA/SST turbulence model available in github is in fully functional mode now. I tried to run again the similar test case mentioned earlier in this thread, but no success. The code just stopped after performing Mulitgrid agglomeration.
