The present paper deals with the finite element analysis of transient vibration of air in rooms and is a sequel to earlier finite element work presented by Craggs. Results obtained from the finite element model of rectangular, triangular and cylindrical rooms are compared with those given elsewhere

The finite element method (FEM) is used for solving the Schrodinger equation in one dimension. Simple model potentials are selected to compare analytical and numerical results. Within FEM, polynomials up to eighth order are used. A much higher accuracy of the eigenvalues could be achieved, if the si
