SU2 LM Transition Model (v4.1.0 cardinal release)

whizkid · January 21, 2016, 15:49

Hello all SU2 users,

I wonder if anyone has solved ERCOFTAC T3 zero pressure gradient transitional flow on flat plate test cases before.

I try to validate these test cases, but seem to have problems with the KIND_TRANS_MODEL = LM coupled with KIND_TURB_MODEL = SA. Maybe my input file is not proper, but every single time i try, i got the divergence error (tons of lines of output is printed on the command window, related to the transition model parameters and i think that is for debugging purpose?)

If anyone has done it before, would you please share the configuration file with me? As soon as I make sure everything runs smooth and the validations are completed, I will be working on implementing my own promising transition model (AIAA 2013-2531).

Also, it would be great if a tutorial document for at least maybe T3A case is released officially (I know laminar flow and fully turbulent flow over flat plate tutorials are up there, but obviously they do not have the transition model activated).

Thanks in advance!
Best,

Hi whizkid,

the transition model is still under development and not working yet.
