% Temperature gradient grad_T = dN_dx' * T_elem;

%% Plot heat flux vectors function plot_heat_flux_field(coordinates, elements, T, k) % Calculate and plot heat flux vectors matlab codes for finite element analysis m files hot

% Create the mesh x = linspace(0, L, N+1); % Temperature gradient grad_T = dN_dx' * T_elem;

% Heat source Q_dot = 10000; % Internal heat generation [W/m³] % Heat source Q_dot = 10000

% K = Global Stiffness Matrix, k_e = Local Element Matrix % index = Mapping vector from local to global DoFs for e = 1:num_elements nodes_e = element_connectivity(e, :); index = calculate_indices(nodes_e); K(index, index) = K(index, index) + k_e; end Use code with caution.
