In the finite element method for the numerical solution of elliptic partial differential equations, the stiffness matrix is a matrix that represents the system of linear equations that must be solved in order to ascertain an approximate solution to the differential equation. See more For simplicity, we will first consider the Poisson problem $${\displaystyle -\nabla ^{2}u=f}$$ on some domain Ω, subject to the boundary condition u = 0 on the boundary of Ω. To discretize … See more Determining the stiffness matrix for other PDEs follows essentially the same procedure, but it can be complicated by the choice of … See more In order to implement the finite element method on a computer, one must first choose a set of basis functions and then compute the integrals defining the stiffness matrix. … See more WebJul 26, 2024 · When it is difficult to interpret, it can be compared with the diagonal stiffness elements of the intact structure giving easy to understand results.
