Hi everyone,

Im trying to run an incompressible steady state simulation with the LRR turbulence model (simpleFoam). I started off with k-epsilon until fully converged then setup the LRR case. The simulation starts off well then becomes unstable after a few iterations.

Attached some case files, geometry section and residual plot. I did not include the U file as it is too big. If someone has an idea of what is wrong please let me know.

Many thanks
