Hi Fluent users,

i have question like while runnig the iteration my solution is not converging, the residuals are diverging.

first iam solving for a steady case, laminar flow. the boundary condition are

(1)inlet-outlet are periodic - type translation (2)side faces are also periodic - type rotational (3)Walls are of constant temperatures

the residuals are set up for 10e-05 for convergence criterion . plz help as iam not able to proceed further. still if u cant able to understant it. let me know i will try to explain in detail. if u want me to send the geometry, i can do that also.

thanks in advance,
