Hi,
This problem concerns a vehicle body with a heated radiator in a duct. I got it working in OF8 with the generous help of the members of this forum. Now, I am trying to get it to run in OpenFOAM 9. Apparently, many of the changes in OF9 concern heat transfer, so I am putting myself through the wringer. Of course it fails; the error output is in the attached file 'run-error.txt'. The place where it actually suffers death throes is here: Code:
Creating fvModels from "constant/fvModels" Selecting finite volume model type fixedTemperatureConstraint [0] [1] [1] [1] --> FOAM FATAL IO ERROR: [1] Unknown fvModel fixedTemperatureConstraint Valid fvModels are: 23 ( accelerationSource actuationDiskSource buoyancyEnergy buoyancyForce coded effectivenessHeatExchangerSource explicitPorositySource heatSource heatTransfer interRegionExplicitPorositySource interRegionHeatTransfer isotropicDamping massSource phaseLimitStabilisation radialActuationDiskSource radiation rotorDisk semiImplicitSource sixDoFAccelerationSource solidEquilibriumEnergySource solidificationMeltingSource verticalDamping volumeFractionSource ) Code:
FoamFile { format ascii; class dictionary; object fvModels; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // /* fixedTemperature { type fixedTemperatureConstraint; selectionMode all; mode uniform; temperature constant 300; // Set temperature (K) } */ /* fixedPower { type heatSource; selectionMode all; Q 100; // Set power (W) } */ I am hoping for insights as to this problem, and maybe even an explanation of the structural differences for this type of case, between OF8 and OF9. Thanks again, community! |

share the case setup or the fvModel file. will check what might be the problem

In OpenFOAM v9 all fixed constraints are defined in fvConstraint.
It's one of the changes from OF8 to OF9, the fvOptions are separated into two parts which are fvModels and fvConstraint. If I'm not wrong fvConstraint is located in the system directory and the fvModels is located in the constant directory. |
