This paper deals with comparison of two low-order finite elements used to describe homogenous incompressible flow in two dimensions with Eulerian description. The governing equations are presented as well as their discretized form obtained using traditional Galerkin method. Necessary stabilization techniques are discussed, allowing using interpolations violating LBB condition, application to convection-dominated problems, etc. The elements are compared on an example of lid cavity driven flow.
