Hello,

I am running a simulation over a fin, I have two options either to give periodic boundary condition with user defined pressure jump, given by:

P(x,y,z)=−βx+p(x,y,z)

Here, β is the linear component of the pressure and p(x,y,z) is periodic pressure component. β=(Pressure inlet-pressure outlet)/fin length.

My second option is to map the simulation data from outlet and initialize it as an inlet to achieve a fully developed flow condition. Can someone help me with this ?
