Hello guys!!!
I need a help. I am new to OpenFOAM as well as CFD. so kindly help me. I need to apply time varying heat flux as boundary condition. I know that there is wallHeatFlux. I tried to use wallHeatFlux in T as follows: Code:
patch76 { type wallHeatFlux; value uniform 1; } patch78 { type wallHeatFlux; value uniform 1; } patch80 { type wallHeatFlux; value uniform 1; } Code:
Reading thermophysical properties Selecting thermodynamics package hPsiThermo<pureMixture<sutherlandTransport<specieThermo<hConstThermo<perfectGas>>>>> --> FOAM FATAL ERROR: Not Implemented Trying to construct an genericFvPatchField on patch patch76 of field h From function genericFvPatchField<Type>::genericFvPatchField(const fvPatch& p, const DimensionedField<Type, volMesh>& iF) in file fields/fvPatchFields/basic/generic/genericFvPatchField.C at line 45. |

take a look at groovyBC, maybe that can help you out. I am not sure if you can specify the heat flux, but time varying is definitely possible.

thank you!! i will look at that...
Can anyone tell me if it is possible to give heat as a bc. like x joules heat coming from an internal heat source (like a wall or something??) Last edited by robingilbert; February 19, 2010 at 16:37. |

Did you ever have any luck in finding a way to add a heat flux boundary condition?
Thanks |
