I need help with this assignment too, I have done the derivation of the FDM but I cannot get any ablation on the material, can you provide some hints? The assignment asks for the full derivation of the final FDM equation using the explicit finite difference method for the data provided for group $1$ and using the parameters in row $1$ for the material and laser properties. Then present the code using MATLAB or C$++.$ There should be one graph showing the ablation on an x$-$z plot and a temperature distribution graph. Use the initial $2$D conduction equation and insert the volumetric heat source energy and the gaussian profiles and all the necessary parameters, boundary conditions and time and spacial increments.
