I am trying to implement a boundary condition where the temperature gradient in the normal direction to the wall is -1. how do i do it. i am using heat transfer in fluid physics and laminar flow physics. and in a wall i have to set temperature gradient in the normal direction to the wall to -1. is there any way i can do that?

Hello,
Use a "Heat Flux" bundary condition. You can find it by right-clicking the Heat Transfer in Fluid node. Select a boundary and it will impose the following condition : 
is the temperature gradient, also called heat flux. You can assigned the value you wish in the field q0.
Hope it helps !
