% Area area = 0.5 * abs((x(2)-x(1))*(y(3)-y(1)) - (x(3)-x(1))*(y(2)-y(1)));

% Number of nodes and DOFs (1 DOF per node for axial) n_nodes = length(nodes); n_dof = n_nodes; matlab codes for finite element analysis m files

% --- Solve --- U = K \ F;

% Element stiffness matrix ke = thickness * area * (B' * D * B); % Area area = 0
