Hello Guys
I hope you all having the good weekends!! I am simulating multi phase flow in the Helical pipe and for this I am using the damBreak case as reference. But I am getting the error as follow. I have attached the ZIP file of the simulation files (file is double zipped due to size issue) Thank you for your help in advance Create time Create mesh for time = 0 Selecting solver compressibleVoF Selecting thermodynamics package { type heRhoThermo; mixture pureMixture; properties liquid; energy sensibleInternalEnergy; } Selecting thermodynamics package { type heRhoThermo; mixture pureMixture; transport const; thermo hConst; equationOfState perfectGas; specie specie; energy sensibleInternalEnergy; } No MRF models present Selecting surfaceTensionModel liquidProperties Courant Number mean: 0 max: 0 Interface Courant Number mean: 0 max: 0 Selecting turbulence model type RAS Selecting RAS turbulence model kEpsilon Creating fvModels from "constant/fvModels" Selecting finite volume model type compressible::VoFTurbulenceDamping Name: turbulenceDamping PIMPLE: No convergence criteria found PIMPLE: Operating solver in transient mode with 1 outer corrector PIMPLE: Operating solver in PISO mode Starting time loop Courant Number mean: 0 max: 0 Interface Courant Number mean: 0 max: 0 deltaT = 1.19904e-05 Time = 1.19904e-05s smoothSolver: Solving for alpha.water, Initial residual = 0, Final residual = 0, No Iterations 0 Phase-1 volume fraction = 0.5 Min(alpha.water) = 0.5 Max(alpha.water) = 0.5 MULES: Correcting alpha.water MULES: Correcting alpha.water Phase-1 volume fraction = 0.5 Min(alpha.water) = 0.5 Max(alpha.water) = 0.5 smoothSolver: Solving for Ux, Initial residual = 0, Final residual = 0, No Iterations 1 smoothSolver: Solving for Uy, Initial residual = 0, Final residual = 0, No Iterations 1 smoothSolver: Solving for Uz, Initial residual = 0, Final residual = 0, No Iterations 1 --> FOAM FATAL ERROR: request for surfaceScalarField phi.gas from objectRegistry region0 failed available objects of type surfaceScalarField are 8 ( rhoPhi ghf alphaRhoPhi.water phi nHatf magSf alphaRhoPhi.air alphaPhi.water ) From function const Type& Foam: ![]() in file /home/ubuntu/OpenFOAM/OpenFOAM-11/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 211.

Hello Guys
I hope everyone is doing well I am working on the project of multi phase simulation of helical pipe, for this case I am using the multi phase Euler foam, but I am getting the following error --> FOAM FATAL IO ERROR: keyword pSat is undefined in dictionary "gas_liquid_inThe_gas/gas_liquid_inThe_gas" file: gas_liquid_inThe_gas/gas_liquid_inThe_gas from line 115 to line 121. From function const Foam::entry& Foam::dictionary::lookupEntry(const Foam::word&, bool, bool) const in file db/dictionary/dictionary.C at line 827. even after changing the phaseProperties file I am getting the same error Here below i have pasted my phaseProperties file /--------------------------------- C++ -----------------------------------\ ========= | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox \\ / O peration | Website: https://openfoam.org \\ / A nd | Version: 10 \\/ M anipulation | \---------------------------------------------------------------------------/ FoamFile { format ascii; class dictionary; location "constant"; object phaseProperties; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // type interfaceCompositionPhaseChangeMultiphaseSystem; phases (gas liquid); gas { type multiComponentPhaseModel; diameterModel isothermal; isothermalCoeffs { d0 3e-3; p0 1e5; } residualAlpha 1e-6; } liquid { type multiComponentPhaseModel; diameterModel constant; constantCoeffs { d 1e-4; } residualAlpha 1e-6; } blending { default { type linear; minFullyContinuousAlpha.gas 0.7; minPartlyContinuousAlpha.gas 0.3; minFullyContinuousAlpha.liquid 0.7; minPartlyContinuousAlpha.liquid 0.3; } heatTransfer { type linear; minFullyContinuousAlpha.gas 1; minPartlyContinuousAlpha.gas 0; minFullyContinuousAlpha.liquid 1; minPartlyContinuousAlpha.liquid 0; } diffusiveMassTransfer { $heatTransfer; } } surfaceTension { gas_liquid { type constant; sigma 0.07; } } drag { gas_dispersedIn_liquid { type SchillerNaumann; residualRe 1e-3; } liquid_dispersedIn_gas { type SchillerNaumann; residualRe 1e-3; } } virtualMass { gas_dispersedIn_liquid { type constantCoefficient; Cvm 0.5; } liquid_dispersedIn_gas { type constantCoefficient; Cvm 0.5; } } interfaceComposition { gas_liquid_inThe_gas { type saturated; species ( water ); Le 1.0; saturationPressure { type ArdenBuck; pSat 3000; // I have updated pSat here } } gas_liquid_inThe_liquid { type Henry; species ( air ); k ( 1.492e-2 ); Le 1.0; } } heatTransfer { gas_dispersedIn_liquid_inThe_gas { type spherical; residualAlpha 1e-4; } liquid_dispersedIn_gas_inThe_gas { type RanzMarshall; residualAlpha 1e-4; } gas_dispersedIn_liquid_inThe_liquid { type RanzMarshall; residualAlpha 1e-4; } liquid_dispersedIn_gas_inThe_liquid { type spherical; residualAlpha 1e-4; } } diffusiveMassTransfer { gas_dispersedIn_liquid_inThe_gas { type spherical; Le 1.0; } liquid_dispersedIn_gas_inThe_gas { type Frossling; Le 1.0; } gas_dispersedIn_liquid_inThe_liquid { type Frossling; Le 1.0; } liquid_dispersedIn_gas_inThe_liquid { type spherical; Le 1.0; } } phaseTransfer {} lift {} wallLubrication {} turbulentDispersion {} interfaceCompression {} // ************************* // I hope someone can help me with this.
