2D Heat conduction steady state transient analysis

Objective: heat conduction equation (diffusion equation) `(∂T)/dt+α∇^2 T=0` `(∂T)/dt+α((∂^2 T)/(∂x^2 )+(∂^2 T)/(∂y^2 )+(∂^2 T)/(∂z^2 ))=0` BOUNDARY CONDITION Square plate with equal number of grids Length of domain l=1 Number of grid n=11 So length in x & y are same (l=lx=ly)…
