LamBremhorst turbulent modelHi,
i'm testing OpenFoam with the simple Restivo case. Can't get the Low-Reynolds LamBremhorst model to converge. Epsilon always gets infinite and nut to zero. Works ok with Launder-Sharma model. Also, Mesh is fine enough for a LRN model. Any advice? Experiences with the LamBremhorst model? Thanks |

Hii Jo,
Any chance you managed to solve this problem?? I too am encountering this problem at the moment. Any help you could pass on?? I am implementing simpleFOAM to run a simple 2D flatplate case. I am stuck with assigning the boundary condition for epsilon at the wall. Would be really great if you can help!! Thnks Nikesh |

Hi Nikesh,
The only way I could get the LRN LB model to converge is with a very dense mesh near the boundaries. This is equivalent to a direct resolution of the Navier-Stokes equations, no LRN models involved. After multiple tests, I came to the conclusion that the LB model code is not working right, impossible to duplicate any results found in references. Instead of using the LB model, I used a 2 layer LRN model (Xu-Chen) for my applications. Sorry I could not be of more help. Have a nice day. |

Thnx Jo.
I shall try that out too. Lets see how it goes!! |
