Hello there,
I'm struggling with the two-dimensional large-eddy-simulation of the OAT15A airfoil, which is restarted from the RANS results.
my problem is that the shock seems to keep moving upstream until simulation diverges, which can also be seen in the pressure coefficient distribution attached. The cfg file is also attached below.
so my question is, how i can solve this problem?
any suggestions would be appreciated.
