Abstract

The objective of this paper is to present a study of the solvability, stability and optimal error bounds of certain mixed finite element formulationsfor acoustic fluids. An analytical proof of the stability and optimal error bounds of a set of three-field mixed finite element discretizations is given, and the interrelationship between the inf-sup condition, including thenumerical inf-sup test, and the eigenvalue problem pertaining to the natural frequencies is discussed.
