Hi,

Am not so good in programming but am trying to do a simuation of laser ablation using two-temperature model. However, am not able to define boundary conditions correctly which is giving me a false output due to very limited temperature change. Can someone please help me code the boudary conditions for the following equation;

The code am having for the boudary condition is;

function [pl,ql,pr,qr] = pdebc(xl,ul,xr,ur,t) % Boundary Conditions

pl = [0;ul(1)];

ql = [300;300];

pr = [ur(1)-300;ur(2)];

qr = [300;300];

end

and the one for my initial condition is;

function u0 = pdeic(x) % Initial Conditions

u0 = [300; 300];

end

Hey, Do you upload the code to Github or somewhere, I'm a new user of Matlab and I'll like to do the same simulation, nevertheless i can't find more information than this post to move forward.

Thx in advance.

You can refer following MATLAB answer to get an idea about how to define boundary conditions for the equations.

Also the following documentation link contains multiple example that may help you with coding boundary conditions and getting more insight into pdepe.
