function [T_solution, time_vec] = transient_thermal_solver(... K, M, F, T_initial, dt, n_steps) % Transient thermal solver using generalized-alpha method % Inputs: % K - stiffness matrix % M - mass matrix % F - force vector % T_initial - initial temperature field % dt - time step % n_steps - number of time steps % Outputs: % T_solution - temperature field at each time step [n_nodes x n_steps+1] % time_vec - time vector The solver roared to life, iterating through the

Suddenly, the progress bar turned green. The solver roared to life, iterating through the loops with rhythmic precision. The monitor erupted into a vibrant contour plot. The stress concentrations shifted, flowing like liquid fire across the 3D model, but staying just within the safety margin.

: A loop ran through every element, "stamping" its small into a massive Global Stiffness Matrix ( ).
