Hello, Am working on a model that involves heat conduction in a semi-infinite solid. I have been using linspace() command for finite geometry, but now i need to create a 1-dimensional semi-infinite solid. Any suggestions? Thank you.

As you have noticed that i will be needing an extremely fine mesh, I was using a time step of 1ns and a 10nm step for distance x. Is it possible that using these increments might affect the stability of the solution? I would also like to mention that I need to study the behaviour in the first...

Sorry. Forgot to mention about the coefficients earlier. A is a function of T, whereas B,C and D are positive constants.

Hello everyone, I am trying to model the process of laser ablation on a material using MATLAB. The governing equation is of the form: ∂T(x,t)/∂t = ∂/∂x(A*∂T/∂x) + B*exp(-C*t2)*exp(-D*x) with one Initial condition and two boundary conditions. Using the built-in 'pdepe' function in Matlab...
