The symmetric interior penalty discontinuous galerkin finite element method is presented for the numerical discretization of the second‐order wave equation the resulting stiffness matrix is symmetric positive definite, and the mass matrix is essentially diagonal hence, the method is inherently parallel and leads to fully explicit time integration when coupled with an explicit time . This paper is focused on sensible heat thermal energy storage (shtes) systems using solid media and numerical simulation of their transient behavior using the finite element method (fem). Parameterized extended finite element method the finite element method tries to correctly map the energy input from the boundary condition even if the ansatz functions are not able to represent the gradient in a sufficient manner. Finite element energy functional must equal zero the finite element method obtains the correct solution for any finite element model by minimizing the energy.
