Why is this case unstable using SPS-LES?
I am looking at the example folder for mDBC:
And running this case it works fine using artificial viscosity. If I then try to run the simulation using SPS-LES, with a kinematic viscosity of 1e-6, I get an unstable simulation, with a very weird force result generated by the simulation.
Could anyone explain to me how I could go about stabilizing this setup such that I can use SPS-LES?
