Finite element methods for compressible flows
Abstract
The application of finite element methods to steady compressible flows where the velocity is derivable from a potential is examined. In particular, elements which are stable and optimally accurate for incompressible flows yet fail in the compressible case are surveyed. It is concluded that only inclusive elements will yield optimal accuracy for compressible flows. The criss-cross configuration gives second order accuracy to velocities in both the compressible and incompressible cases.
