| Summary | 0004256: Error in multiphaseEuler with massDiffusionLimitedPhaseChange and populationBalance | ||||
| Description | The following error is thrown when using both the models ``` MULES: Solving for alpha.gas MULES: Solving for alpha.liquid MULES: Correcting alpha.gas MULES: Correcting alpha.liquid gas fraction, min, max = 9.56334e-09 -1.17816e-25 0.5 liquid fraction, min, max = 1 0.5 1 Phase-sum volume fraction, min, max = 1 1 1 MULES: Solving for alpha.gas MULES: Solving for alpha.liquid MULES: Correcting alpha.gas MULES: Correcting alpha.liquid gas fraction, min, max = 1.85542e-08 -8.33572e-113 0.5 liquid fraction, min, max = 1 0.5 1 Phase-sum volume fraction, min, max = 1 1 1 populationBalance bubbles: Iteration 1 [24] [24] [24] --> FOAM FATAL IO ERROR: [24] Cannot find fieldSource entry for phaseChange [24] [24] file: unknown [24] [24] From function const Source& Foam::GeometricFieldSources<Type, GeoMesh, PrimitiveField>::operator[](const Foam::word&) const [with Type = double; GeoMesh = Foam::volMesh; PrimitiveField = Foam::Field; Foam::GeometricFieldSources<Type, GeoMesh, PrimitiveField>::Source = Foam::fvFieldSource<double>] [24] in file /opt/openfoam13/src/OpenFOAM/lnInclude/GeometricFieldSources.C at line 251. [24] ``` The error happens when the population balance equations are solved. Commenting out line 579 and 1414 from populationBalance.C removes the error. Thus, the error happens when fvOptions().source(alpha, rho, fi) is called.
