The present work analyzes three different gradient reconstruction procedures, using three different simulation test cases, namely the zero-gradient flat plate, the ONERA M6 wing and the wing-body common research model. Overall increase in algorithm robustness is observed when the gradient-calculation scheme that brings into the formulation the information from the discontinuous solution is used.
