Hi Foamers,

I have a question. It is like this :

I am running the rhoCentralFoam for the flow simulation over OneraM6 wing.
The output of the solver is attached below
================================================== =============
Starting time loop

forceCoeffs forces:
Not including porosity effects

Mean and max Courant Numbers = 1.747831e-05 0.03413952
Time = 1e-08

diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal: Solving for rhoUx, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal: Solving for rhoUy, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal: Solving for rhoUz, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal: Solving for rhoE, Initial residual = 0, Final residual = 0, No Iterations 0
ExecutionTime = 8.03 s ClockTime = 8 s

forceCoeffs forces output:
Cm = 9.136184e-05
Cd = 0.0003770677
Cl = 0.0007398541
Cl(f) = 0.0004612889
Cl(r) = 0.0002785652

Mean and max Courant Numbers = 1.747831e-05 0.03415259
Time = 2e-08

diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal: Solving for rhoUx, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal: Solving for rhoUy, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal: Solving for rhoUz, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal: Solving for rhoE, Initial residual = 0, Final residual = 0, No Iterations 0
ExecutionTime = 11.02 s ClockTime = 11 s
================================================== ============

The solver log shows initial residual and final residual as ZERO(as seen above).
Why is that so ? Plz help.

Gopal.
