I am interested in the new lesBuoyantFoam solver in the 1.5 distribution. I can't see any tutorial cases and I can't find any threads mentioning this solver so far. Does anybody have a test case that could be posted?
Thanks, Simon |

Dear All
i tried lesBuoyantFoam on my case since there is no tutorial cases on this solver, i tried to modify boundary condition, constant and system from BuoyantFoam, coodles and LesInterFoam solvers cases. but i got an error message after some interations on Time = 0.20375 Courant Number mean: 4.715132e-05 max: 0.41762132 deltaT = 0.00125 Time = 0.20375 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 DILUPBiCG: Solving for k, Initial residual = 0.99887462, Final residual = 1.0797669e-08, No Iterations 2 bounding k, min: -1.915483 max: 216.44551 average: 0.11620192 DILUPBiCG: Solving for Ux, Initial residual = 0.065561486, Final residual = 1.4688951e-06, No Iterations 1 DILUPBiCG: Solving for Uy, Initial residual = 0.15697778, Final residual = 2.4897678e-06, No Iterations 1 DILUPBiCG: Solving for Uz, Initial residual = 0.14679518, Final residual = 2.4445675e-06, No Iterations 1 DILUPBiCG: Solving for h, Initial residual = 0.0005069952, Final residual = 1.3786841e-09, No Iterations 1 Maximum number of iterations exceeded#0 Foam::error::printStack(Foam:stream&) in "/home/user/OpenFOAM/OpenFOAM-1.5/lib/linuxGccDPOpt/libOpenFOAM.so" #1 Foam::error::abort() in "/home/user/OpenFOAM/OpenFOAM-1.5/lib/linuxGccDPOpt/libOpenFOAM.so" #2 Foam::hThermo<foam::puremixture<foam::consttranspo rt<foam::speciethermo<foam::hc onstthermo<foam::perfectgas> > > > >::calculate() in "/home/user/OpenFOAM/OpenFOAM-1.5/lib/linuxGccDPOpt/libbasicThermophysicalModels .so" #3 Foam::hThermo<foam::puremixture<foam::consttranspo rt<foam::speciethermo<foam::hc onstthermo<foam::perfectgas> > > > >::correct() in "/home/user/OpenFOAM/OpenFOAM-1.5/lib/linuxGccDPOpt/libbasicThermophysicalModels .so" #4 main in "/home/user/OpenFOAM/OpenFOAM-1.5/applications/bin/linuxGccDPOpt/lesBuoyantFoam" #5 __libc_start_main in "/lib/tls/i686/cmov/libc.so.6" #6 Foam::regIOobject::readIfModified() in "/home/user/OpenFOAM/OpenFOAM-1.5/applications/bin/linuxGccDPOpt/lesBuoyantFoam" From function specieThermo<thermo>::T(scalar f, scalar T0, scalar (specieThermo<thermo>::*F)(const scalar) const, scalar (specieThermo<thermo>::*dFdT)(const scalar) const) const in file /home/dm2/henry/OpenFOAM/OpenFOAM-1.5/src/thermophysicalModels/specie/lnInclude/ specieThermoI.H at line 78.

oh ya,
i set my controldict as shown below: application lesBuoyantFoam; startFrom startTime; startTime 0; stopAt endTime; endTime 0.5; deltaT 1e-04; writeControl adjustableRunTime; writeInterval 5e-03; ............................................ i mix boundary in dictionary from some solvers (those i mentioned above) e.g : LESProperties from coodles epsilon : 0.01 k : 0.1 pd : Walls { type fixedFluxBuoyantPressure; value uniform 0; } any comment and suggestion? |
