 September 11, 2012, 10:09 How to set uniform heating boundary condition? #1 Member   Sangeeta Join Date: Jul 2012 Location: Kingston, Canada Posts: 70 Rep Power: 7 Sponsored Links Hello everyone, I would like to specify uniform heating boundary condition in 0/T file. In my case, an initially unreformed cube is subjected to a uniform temperature rise ΔT = T - Tr (there is no body forces). Tractions are zero at all cube surfaces. It is 3D problem. I have taken a quarter geometry (with 3 symmetry planes). Following are the boundary conditions 0/T FoamFile { version 2.0; format ascii; class volScalarField; object T; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 0 0 1 0 0 0]; internalField uniform 0; boundaryField { left { type symmetryPlane; } right { type fixedValue; value uniform 100; } top { type fixedValue; value uniform 100; } bottom { type symmetryPlane; } front { type fixedValue; value uniform 100; } back { type symmetryPlane; } } 0/D FoamFile { version 2.0; format ascii; class volVectorField; object D; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 1 0 0 0 0 0]; internalField uniform (0 0 0); boundaryField { left { type symmetryPlane; } right { type tractionDisplacement; traction uniform (0 0 0); pressure uniform 0; value uniform (0 0 0); } top { type tractionDisplacement; traction uniform (0 0 0); pressure uniform 0; value uniform (0 0 0); } bottom { type symmetryPlane; } front { type tractionDisplacement; traction uniform (0 0 0); pressure uniform 0; value uniform (0 0 0); } back { type symmetryPlane; } } I have taken initial temp. = 0, and final or heating temp.= 100. Does these are the correct boundary condition for uniform heating? Does anyone have any idea about this? Thanks in advance. Sangeeta
