A Least Squares Finite Element Approach to Unsteady Gas Dynamics.
Abstract
A new numerical technique for solving unsteady gas dynamic equations is presented. The technique is based on least squares finite element concepts with elements that are constructed in both space and time. Both linear and quadratic interpolation is used on individual elements. The technique is tested against a problem whose exact solution is known so that numerical accuracy can be ascertained.
