Hello Foamer,
I am relatively new to openfoam. I want to extract the convective heat transfer coefficient (CHTC) and I am facing some issues. This is my setup: - Geometry : searchableRotatedBox (named panel) - Solver : buoyantBoussinesqSimpleFoam - Meshing : SnappyHexMesh (with layers and refinement regions) - fluide : Incompressible - RAS : kOmegaSST - transportModel : Newtonian 1. direct : using "heatTransferCoeff": Code:
heatTransferCoeff1 { // Mandatory entries (unmodifiable) type heatTransferCoeff; libs (fieldFunctionObjects); // heatTransferCoeff; // Nu : Nusselt number // L : Characteristic length that defines the scale of the physical system // kappa : Thermal conductivity of the fluid field chtc_0; patches (panel); htcModel ReynoldsAnalogy; // options: ReynoldsAnalogy; localReferenceTemperature; fixedReferenceTemperature UInf (20 0 0); Cp CpInf; CpInf 1000; rho rhoInf; rhoInf 1.2; // Optional (inherited) entries result chtc_0; region region0; enabled true; log true; timeStart 0; timeEnd 5000; executeControl timeStep; executeInterval 1; writeControl timeStep; writeInterval 1; } Code:
--> FOAM FATAL ERROR: Unable to find a valid thermo model to evaluate q Code:
wallHeatFlux1 { // Mandatory entries (unmodifiable) type wallHeatFlux; libs (fieldFunctionObjects); // Optional entries (runtime modifiable) patches (panel); qr qr; } Code:
--> FOAM FATAL ERROR: Unable to find compressible turbulence model in the database Can you help me please ? Thank you for you time ! Cheers, Fadi |
