How to define a sliding wall BC in OpenFOAM???
I am new to OpenFOAM. My case is to simulate lamb-oseen vortex in a Cuboid shaped domain. I have given a fixed value for my 'Inlet' , outletInlet for 'Outlet' and wall Bc for the bottom face. I have to give 'Sliding wall" BC to other three faces.
Turbulence model : LES
What does this sliding wall numerically means and how should I implement it in OpenFOAM??? what should I give for U, P, k and nuTilda?
maybe the sliding wall in http://www.openfoam.org/docs/user/cavity.php#x5-40002.1 is enough for you? Very simple. You can set the turbulent variables to zeroGradient at the wall(s), the others like in the tutorial.
Thanks alot.. and I have one more doubt..
I need to initialise lamb-oseen vortex in my domain..I have the u,v,w component equations in cartesian co-ordinates for velocity at time t=0.
1. How can I give a non-uniform velocity profile ?
2. If I can use FunkySetFields, Can anyone please tell me how to use it..?
3. I also have a c coding that generates the required velocity values at every node for my domain, used for FLUENT. Is it possible to use the same coding in OpenFOAM ???
