Hello , I am trying to use the simpleFoam solver for a cylindrical flow for a rotating exhaust fan , but i seem to be getting these errors for every step
The time step continuity error seems to be diverging rather than converging Time = 5 smoothSolver: Solving for Ux, Initial residual = 1, Final residual = 0.091959499, No Iterations 5 smoothSolver: Solving for Uy, Initial residual = 0, Final residual = 0, No Iterations 0 smoothSolver: Solving for Uz, Initial residual = 0, Final residual = 0, No Iterations 0 GAMG: Solving for p, Initial residual = 1, Final residual = 0.077236211, No Iterations 4 time step continuity errors : sum local = 0.0043637581, global = -2.3391276e-08, cumulative = -2.3391276e-08 smoothSolver: Solving for omega, Initial residual = 0.31633517, Final residual = 0.021362197, No Iterations 4 smoothSolver: Solving for k, Initial residual = 0.99999998, Final residual = 0.091347867, No Iterations 14 ExecutionTime = 293.99 s ClockTime = 301 s If possible can someone please help me with this , i am very new to OpenFoam , Thank you here is p file /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: v1912 | | \\ / A nd | Website: www.openfoam.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class volScalarField; object p; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 2 -2 0 0 0 0]; internalField uniform 0; boundaryField { AMI1 { type cyclicAMI; value uniform 0; } AMI2 { type cyclicAMI; value uniform 0; } exhaustfan { type fixedFluxPressure; value uniform 0; } inlet { type fixedFluxPressure; value uniform 0; } outlet { type fixedValue; value uniform 0; } rotating_zone { type fixedFluxPressure; value uniform 0; } } // ************************************************** *********************** // |
