Hi! How do I define the bou
How do I define the boundary conditions for the LRR turbulence model at an inlet, an outlet and a wall?
Is this right?
R_ii = 2/3*k
R_ij = 0 i<>j
i am simulatinf the flow over an airfoil, i use simpleFoam and LRR turbulence model, but my simulation with this model diverged, i don't know why!
did you understand How to define the boundary conditions for the LRR turbulence model at inlet &outlet &wall?
if your simulation is diverging, what you can try is to run k-epsilon for 1000 iterations, then run the R command in terminal. Then go to RAS properties and change k-epsilon to LRR.
At the wall with a wall resolved grid the Reynolds stress tensor should be zero. At the inlet I use fixedValue and zeroGradient at the outlet.
Hope this helps,
Thank you very much:)
