**A simple finite element method simulating the incompressible high Reynolds number flow and boundary layer separation**

In this talk, we apply a simple finite element numerical scheme, to perform a high resolution numerical simulation of incompressible flow over a triangular domain and analyze its boundary layer separation. Compared with many classical finite element fluid solvers, this numerical method avoids a Stokes solver, and only two Poisson-like equations need to be solved at each time step/stage. Numerical experiments over triangular domain for high Reynolds number $Re=10^4, 10^5$ flows are investigated. At same time, the dynamical mechanism of the boundary layer separation, including the bifurcation location and critical time are qualitatively reported in this talk.
