About cyclic boundary condition
 
Hi Foamers,

I am trying to use cyclic BC. For the velocity i got good results.
But in my solver i have one more field (let say T). At the inlet for the field T, i need to specify fixed value. Where as for outlet my boundary condition is zero gradient. My case is 2D channel flow. I required cyclic boundary for inlet and outlet only. At walls the boundary condition for T is zero flux.

For the velocity a pressure gradient is added to the momentum equation. Like wise could you please tell me how to add gradient for the field T.
My solver is steady state and flow is laminar flow. I prepared my solver by modifying simpleFoam solver.


Thanks
