Bzier versus Lagrange polynomials-based finite element analysis of 2-D potential problems
We show that the usual Lagrangian type finite elements are equivalent with Bzierian type ones. Both formulations are applied to the solution of elliptic, hyperbolic and parabolic problems. For both macro-elements we present in house MATLAB software. Extension to linear elastic analysis is straightforward. Extension to 3D problems is also straightforward.
