Strange Temperature Profile simulating laser heating

Please login with a confirmed email address before reporting spam

I am simulating the laser heating of a structure using the formula

to take into account the Reflection at the surface, the absorption of each material and a flat-top intensity distribution given by The structure consists of a narrow slot (actual image of the structure: 1). As it can be seen in the image the slot(red) is filled with a material with thermal conductivity and it is surrounded with a material(blue) with a thermal conductivity at the bottom there is another material with thermal conductivity and whose lower boundary is kept at . Red and blue materials have the same absorption coefficient . What I found strange about the simulation is I get a Temperature profile at the surface of the structure where the laser heating occurs with a very big temperature peak at the position of the slot (image:2 ). Could this be because of a problem with the boundary conditions or the meshing or could it even be correct? Thanks if anyone can help.
