I Cant able to include heat flux in the boundary condition(Neumann boundary condtion)

Hi all, I am very new to OPENFOAM and CFD.I tried to include heat flux in a 2D heat conduction for a rectangular section in unsteady state using laplacianFoam solver. I referred boundary conditions in OPENFOAM site, But I can't be able to sort it out. If anyone could help, please ping me.

Hi Tamil,

You're looking for externalWallHeatFluxTemperature or fixedGradient boundary conditions. Here is the some sites:
