A nine-node quadrilateral FCBI element for incompressible fluid flows. (English) Zbl 1125.76041

Summary: We propose a nine-node flow-condition-based interpolation (FCBI) finite element for the analysis of 2D incompressible flows. Emphasis in the FCBI approach is on obtaining an element that is stable and can be used in rather coarse meshes even when considering high Reynolds number flows. The formulation of the element is presented, and the results of some test cases are given.
