Dear sahilbhapkar30,

if I understood correctly, you would like to implement a Dirichlet boundary condition (BC) for advection-diffusion equations, which is possible in OpenLB via setAdvectionDiffusionTemperatureBoundary2D.

An exemplary implementation of this type of BC is given in the examples/thermal/porousPlate2d(3d).
In the 2d case, you might want to switch to
#define TemperatureBoundary
//#define RegularizedTemperatureBoundary
//#define RegularizedHeatFluxBoundary
to observe the corresponding results.
