Thank you I will try this way and what about changing the Thermal Diffusion "k" value in this step-26 case. As currently it is 1 but if I want to change it shall I multiply value of "k" thermal diffusivity with Laplace Matrix "A" or is there another already developed way in deal.ii ? Thank you in advance!
